  1. i have oced my Intel Core 2 Quad Q8200 @ 3.02Ghz (1820Mhz FSB, 1.45 vcore) and my DDR2 Transcend Xram (5-5-5-15) is on 1098Mhz & my mobo is Asus Rampage Formula X48. Will they b able to feed 2 Ati Radeon 6870 on xfire? I have 1 XFX 6870 in my Rig recently. I also wonder is my cpu @ overclocked speed bottolnecking my single 6870? I also intend to OC my Graphics card (to 1000+Mhz Gpu & 1250+Mhz Gram) will then my cpu b a problem? If will how much?
    Any help will b appriciated......

    the hd 6870 need a quad core to run it at full speed

    There might be a slight bottleneck, but a really small one. I have a DualCore CPU from AMD and I am getting a hd 6950. I am going to upgrade late on, I think you should do the same.

    thats not actually true a duel core that is overclocked good will run it just fine although some games will like to have a quad for better gameplay. At 3.0 Ghz you may be bottlenecking just a little. Also SKYSTAR he is running a quad if you read his post.

    Need more spacific reply

    Some of u have replyed & helped me much. I'm greatful. But i need more specific reply. U guyes didn't say anything about Xfire & Overclocking my Graphics Card on my mentioned system & approximate bottlenecking conditions. Please guyes need help pritty badly......

    yes it will be a bottleneck for 1 or crossfire imo ur best bet is to overclock that cpu to around 3.5 Ghz to get the best from the 6870 also unless you are playing at above 1920x1080 resolution one 6870 should play any game out with no problems.

    If I am correct, anything around 3.0GHz is very good on the Q8200 CPU as its not the best overclocker. I had issues getting much past 3.16GHz on the Q8300 myself.

    So that overclock is good, but I wouldn't push it further.

    I also agree with everyone else that it will bottleneck slightly, but you'll still see worthwhile gains in performance even with the bottleneck.

    the Conclusion :
    Q8200 @ 3.00Ghz = hd 6870
    intel i7 or i5 or phenom x6 = 2x hd 6870

    Thanks Kalipto12, Leepy, SKYSTAR , Atham for your replies & opinion. Your opinions were greatly helpful.
    But i need final words on CrossFire of 6870. Will it be very leggy, i mean will my Q8200 @ 3.02Ghz b a great bottleneck for a 6870 crossfire? Won't i get much benefite from that Xfire? How much diffirence u guys think there will be from a i7 or i5 processors?
    Again thank u guys.

    if you want to get the full benefit from 6870 crossfire , it is important to upgrade your cpu first to at least intel i5 or amd phenom II X6

    if you get the other hd 6870 without upgrading your cpu you will not benefit a lot from crossfire perfomance

    You will still see an increase in performance with 2 GPUs. Its not like the 2nd one won't work or something, and changing chipset is going to get very expensive.

    Thanks Guys. Special thanks 2 Leeky & SKYSTAR.....

    Don't worry. 2 6870s will get the cr*p out of your PC. BTW, what games will you play? If it is Dragon Age II then that is mostly GPU oriented. Just get the other GPU. Make sure your PSU will handle it though.

    Good luck :grinthumb

    i'm gonna play future coming games like Battle Field3 upcoming Call Of Duty etc. at Highst Settings on 1680X1050 @ 60Hz single monitor (Philips 220CW).
    I'm not worried about my PSU. Because it's 850W Quad 12v rail & 34Amps on each 12v rail. I'm consurned about my CPU (Q8200 @ 3.02Ghz).
    thanks Atham.....

    2xHD6870s is complete overkill for 1680x1050, one would more than suffice. As for the Core2Quad@3GHz, it wouldn't bottleneck 1 6870, but it probably would for 2 since you'll be gaming on a relatively low resolution, meaning that because the GPUs are underutilized, the processor comes more into play.

    If you really want your upgrade to be worthwhile, either get a higher resolution monitor to go with 2x6870s, or sell your 6870 and go for a 6950 AND a new monitor.

    You might as well buy that second 6870; it's going to give you more performance, and you can still use them when you upgrade your CPU.

    BTW, I wouldn't agree with two 6870s at 1680X1050 being complete overkill; I happen to have a very similar setup and I can still notice lag on games like Crysis and The Witcher 2 on my 1440X900 monitor.

    If that's the case, it's most likely your Q8200 to blame. 2 6870s easily surpass a GTX 580, and I'm sure you wouldn't suggest that one of those isn't overkill for gaming under 1920x1080.

    Unless you plan on ONLY playing Crysis/Metro2033/Witcher2, that xfire setup is definitely more than you need for that resolution.

    *If you really don't think so, look at the performance review of the 6850 & 6870 xfire, with testing done on an i7 920 @ 3.7GHz

    I had a q9550 which insanely bottlenecked 2x gtx 280s, I eventually got a 580, thinking a single card wouldn't bottleneck as much, but it was the same. Games ran fine in singleplayer but once you get in a 32 player game (more CPU demanding), like crysis, bc2 or gta4, the CPU cant handle it and your frames drop. You'll need an i5 or x4 to rid the bottleneck

    a q9550 at 3.8 ghz will not bottleneck that bad even with a gtx 580 the q9550 is a beast of a cpu even know.

    but the big problem with the q9550 that it hasn't L3 cache and most of the new games require L3 cache to run at high fps .

    klepto12 TechSpot Paladin Posts: 1,364   +9

    SKYSTAR i dont know where you are getting all of your info but i don't find it very helpful the q9550 is still a very fast cpu for most every thing you do except for a couple of games maybe and L3 cache doesn't make that big of a difference. Please make sure that you post accurate info to help the OP.

    In most games the Q9550 at 4.0 Ghz is almost on par with the i7 920 at 4.0 Ghz there are exceptions

    klepto12 :
    the q9550 is like the amd athlon II x4 645 it is a quad core cpu without L3 cache ,in many games the phenom II x2 (dual core cpu) will beat the amd athlon II x4 due to it's L3 cache
    see the huge role of L3 cache in duke nukem review here
    http://www.techspot.com/review/411-duke-nukem-forever-performance/page6.html
    and in deus ex here :
    http://www.techspot.com/review/436-deus-ex-human-revolution-performance-test/page7.html
    and did you ask your self why your cpu (i5 2500k sandy bridge ) has only L3 cache ???????????
    the answer : because the sandy bridge series is especially for extreme gaming and extreme gaming require L3 cache not L2

    Ok Ask the techspot crew and see who is right? also the q9550 has 12mb of L2 cache not 512k like the cpu you posted and is on par with the i7 920 look up the benchmarks and see for yourself DNF was a crappy game and very few games are L3 dependent so your remark is mute.
