    Probably because these things are never black and white. There are elements of truth found throughout the posts regardless of stance/allegiance. The problem comes when the discussion turns into a group of people talking at each other.
    You're never going to get consensus where graphics cards are concerned since user experience plays a large part in how you view the product and the company that made it- and user experience varies wildly depending upon what games/apps are used, hardware fit-out, OS, age or deterioration of components. Add in the rapid nonsensical allegiance that some seem to owe to a faceless company whose prime directive to separate you from your money at any cost, and its a wonder that any two people agree.

    Is the HD 7990 a great card ? IMO no, but I'm not a fan of dual-GPU cards to start with. The more complex the card, the more oft it is to fail. Driver support is usually late to mature and early to cease.

    Someone here said they thought you were thirteen years old. I'm inclined to think that an optimistic projection.

    Well done.

    In answer to the rant :" BTW you never responded on how you were incorrect on your statement regarding the 2win cards " posted below- check the original post. It's called "editing", and much like "quoting" correctly, and "multi-quoting" negates the need double posting.
    "Data center manager" - yeah, right!

    Says the 40 Year old chef who can copy from Wikipedia.

    Yeah Ill get my expertise from real computer experts, not from someone who obviously just googles and copies and pastes his responses to make himself sound smart. BTW you never responded on how you were incorrect on your statement reguarding the 2win cards. What cant take being called out for being wrong?

    Once again your the one going right back off subject.

    Well, I dont hate anyone in this thread, but GhostRyder, if Zero didnt write that history of modern graphics article, but instead copied it, he would be sued instantly.

    Its called google, anyone can type whatever they want, and read about anything and then post it.

    He acts like an expert and wants to call out people on their mistakes, but then he makes one and ignores it by heading straight to insulting the person who called him out on it.

    I hope you are not talking about dividebyzero. I've never known him to take a personal stance toward AMD or nVidia. He has equal knowledge for both parties and will present a fair stance for either side. You would be wise not to refute him, unless you have done your homework.
    And what is it you are doing?

    Im defending the HD 7990 from amstech who comes on here saying NVidia are always superior while divide is being rude and acting like he knows everything about anything. I made one mistake in my logic and he has not shut up since then, then I called him out on it and now he running his mouth with insults.

    Typo, meant to say I called him out on him making a mistake on his logic now hes running his mouth trying to cover it up.

    Yeah, I Was figuring out how to use that Gyazo thing lol

    To view or use gyazo? Its a DL program that once you turn it on, each time its active click and drag. Or the link should just pull up a screenshot.

    Yea correcting your post after your wrong and got called out on it, you only did it to try and fix it after you started ranting (And also your still wrong, EVGA did not disable it, Nvidia physically limited the onboard chipset to only allow 2 GTX 460s/560s in SLI, not EVGA (Hence why EVGA left it on their hoping NVidia might open up a patch to allow this so people could pick up 2 of those which would have bee a cool thing).

    Ill ignore your last statement since your maturity level is just dropping by the second and your just hoping for a response. Grow up.

    I hope AMD brings back the dual GPU cards from the past like a 7870x2 board. And EVGA should make a 660Ti 2Win again.
  16. GhostRyder

    GhostRyder TechSpot Evangelist Posts: 2,177   +511

    I agree, I liked those cards and the ideas behind them. It gave consumers more flexibility in buying multi-GPU setups without spending a fortune. If they do a 660ti hope it will allow 4 was sli and for the 7870 X2 not be too expensive early in the game.

    AMD is said to be working on a 7730, I doubt they are gonna focus on another dual GPU nightmare. Maybe in the 800 series.

    Umm, yeah. That's the way it usually works- and I have no problem holding up my hand when I impart wrong information. Anyhow, the example wasn't pivotal to the point- merely an illustration. The central argument was why you were using a non-reference TUL designed HD 6870 X2 to "prove" that the 6870 was quad-Crossfire capable, while writing off the TUL designed HD 7990 because it is a non-reference design.
    Something I might add, that you haven't addressed.
    Your nose is out of joint because everyone doesn't share your Walter Mitty world view, and because I called you on your successive backpedalling on Crossfire support ( firstly that all Crossfire capable cards support 4-card CFX, then that the 7850/7870 don't either, and then followed by your assertions that the 6870 did (it didn't), and that the GTX x60 only support 2 card SLI when the 660 Ti has 3-way SLI support.
    Yes and No.
    EVGA uses the stock GTX 590 PCB for the 560Ti 2Win which is why the SLI finger is on the board. The SLI finger is operational, EVGA deigned not to try a workaround almost certainly because of Nvidia pressure. There is no "chipset" on the board. The quad-SLI is a lockout at driver/device ID level..., although that hasn't always stopped EVGA - their GTX 285 Classified was the only version to support quad-SLI for example, likewise EVGA also implemented limited 45nm Wolfdale support for the 680i SLI motherboard when other board vendors (XFX, Biostar, Albatron etc) did not.

    I would also take issue with your libellous claim that my articles are "cut and paste". Making such claims without demonstrable proof on many sites usually leads to censure.

    On an unrelated matter:
    So you understood the edit function by post #136, yet still continue to double post in #138 and #139

    I stated that comparing non-reference designs to reference is pointless in terms of cooling and features because a non-reference is designed to be an "Upgrade" per say in terms of being overclocked, better coolers, or things like that. Comparing them is pointless because its whatever the company desided to employ and in this reguard the PowerColor HD 7990 Devil or Non Devil had a 3 slot designed cooler with some different features where as this new one is dual slot and looks pretty much exactly like the HD 6990 in terms of connectors, just a new cooler design.

    I stated that I did not notice that you didnt have the option as the HD 800 series cards did not have the dual connector because I have a friend who said he was running quad 6870's but as I found out when I asked him it was those HIS 6870 X2 Cards which wer non-reference once again proving it was possible even without the connectors and I was looking at last night a 7970 when I thought it was a 7870 by XFX because instead of using newegg I googled 7870 XFX. I even said mistake on my part after you corrected me the second time but you insisted this one issue in my logic was ruining my whole argument. So when you responded with your claims on the 2win cards and I did the same thing to prove a point to the way you were acting, you turned defensive posting rude pictures and acting like a spoiled kid who lost an argument till those other people started coming on, then you acted like you had done nothing and started changing your posts to act mature again.

    Yet you still constantly bring back to these points even when we are all trying to talk about the HD 7990 or AMD cards in general on an AMD review. Which proves my next point that your as you would put it "Nether Region Hurt" because you realised I was right and could not stand being wrong.

    FYI, looking up the 2win cards through google then posting knowlege you obviously did not know an hour ago and acting like you knew this all along does not make you a GPU genious.

    Last thing, again ill repeat myself, grow up and get off this area if your going to continue your little rant because you lost a conversation to someone you look down on. Your supposed to be a 49 year old, act like it and stop acting like a know it all.

    As for the double post before, yea its called an accident, I thought I was editing my post and I made a new one. Get over yourself, if I could have deleted it, I would have.

    JC713 Yea I doubt AMD will, I mean those were made by HIS and Powercolor I believe last time so it would have to rely on them making em again or another company. Seems like AMD is focusing on getting just a wide range of single GPU cards for the time being.

    Can we please stop this flame war. I like you Zero and I like you too Ghost. Live together my friends. Enjoy the beauty of TechSpot! It is meant to be a place were we share ideas and help others out. Heck! We may get into a debate, but we dont push it to the point where hate is how we get out message through! You are both putting forth great points, but this has got to end. 4-5 pages of just flame wars, come on guys! As I said before, I like you both :). Just please, enjoy TechSpot for what it has to offer and let us live in harmony :D.

    Actually, what I did was PM one of the EVGA support guys on their forum. I find that it generally yields better and more concise results than Google.

    I have been trying, but since you say it, im going to just stop responding to the guy period. I want to just talk with people about the card and AMD in general since that what the point of this area is.

    JC713 TechSpot Evangelist Posts: 6,846   +887

    I understand, I see what you are trying to do. Same with Zero. You are both trying to prove your sides. This can go on forever, but for your own good :eek:, it should stop before we get AMD and nVidia executives on your doorsteps! LOL.

    The issue really isn't Nvidia vs AMD , for me at least.
    If you check my posting you'd see that apart from supplying some links to clear up some FUD, my comparison is the HD 7990 reference versus the non-reference TUL designed HD 7990 and Crossfired HD 7970 GHz Edition. Two solutions that make more sense for the enthusiast with their balls-to-the-wall approach to overclockability ( cheapo voltage locked versions notwithstanding).

    The AMD vs Nvidia thing doesn't actually make a great deal of sense if you think about it. The GTX 690 -which would be Nvidia's analogue of the 7990, has already been out for a year. Anyone who was after a duallie probably would have acted by now- but sales of the card aren't particularly heavy. It's only saving grace is that it exhausts all of the hot air it generates outside the chassis and is good fit for small form factor rigs. Anyone who bought a GTX 690 isn't going to "upgrade" to a HD 7990 for a minimal gain- especially with a Kepler refresh only a couple of months away, and how many present owners of 7970 and 7950 are going to opt for the card knowing it will cost significantly more once they factor in the resell value of their present cards?
    AMD released this card primarily as a PR counter to Nvidia's Titan (even though it isn't for the same buying demographic). The company caught some flak from relying upon board partners for providing the flagship - notably is the Q&A AMD fielded where they countered the Titan's PR blitz with the $1600 Asus Ares II rather than an AMD designed reference card.

    As I noted earlier, the saving grace for the HD 7990 is that it is a hashing monster. An ATX motherboard will accommodate four cards ( 8 GPUs), or as many as seven cards (14 GPUs) using a workstation board, PCI-E risers, and a chassis with 14+ expansion slots (such as those adapted from LD/Caselabs chassis or 4U rackmount), but it has still been done before with the TUL designed HD 7990 - which AMD seems to have abolished.

    As to the HD 7990's place in history, I'd keep note of verified user reviews on Newegg. If AMD have taken a year to get this card out the door, then the binning requirements for GPUs to use with the card are very stringent indeed.

    I Currently own an "AMD" card because I couldn't afford an Nvidia card -_- I don't hate ATI, They used to be my favorite cards until I got the GTX285 which was just the smoothest card I've ever owned, and still use to this day.

    Ok, I'll go back to the 7990, simply put, its not that impressive, end of story. I would purchase one if they gave it some proper overclocking headroom but they haven't, so I don't want one and don't think its particularly good considering its $1000 (that's a lot of money just FYI) and it can't even play Assassins creed.

    Now I know your going to go "your just picking on one thing that doesn't work" but you know, for fact, that loads of Crossfire profiles are missing for modern and older games, I mean, Assassins Creed is extremely popular, surely someone at AMD should check this kind of stuff?

    I'm confused by one thing though, you claim you've been building machines longer than me, you insult other users on here with age jokes and down right calling other users on here liars, yet you argue persistently with no facts but just insults? Examples below:


    I could keep going, but its almost embarrassing...
