Phenom II 1055 - Crosshair 890fx- what else to get

    I decided after much debate to get a AMD Phenom II 1055t processor, with the Asus Crosshair IV 890fx motherboard, and I'm already drooling thinking about it. That is around $400 for those components and I want to keep the build under $900.

    I now need to decide on PSU, Memory, Vid card and case.

    I don't need anything fancy in a case, I'm just looking for something functional, maybe mildly pretty, so I'm thinking around $50ish range. Likewise with PSU, it doesn't need to glow blue or anything, just needs the required wattage.

    So I guess approximately $400ish for memory and vid card. I don't need 16 gig off the bat, am thinking around 4 gig.

    Video card I'm thinking either something real cheap so it won't matter that much when I pull it out to upgrade in the future, or somethign i can crossfire in the future.

    Any tips are appreciated.

    That PSU is kinda weak. I'd at least go 800w. 650w just doesn't leave too much room to play with, with that configuration. especially if you want to add a 2nd card in sli/crossfire. Picking out a case is a personal thing man, just get on Newegg and pick something you like.

    Thx for the tips, all good suggestions.

    I only listed case in here cause looking at them online is daunting, like 50 of them look exactly the same and cost the same.

    I disagree...

    Don't forget the gtx 470 either, I'm not sure what the pricing is like in America but in the UK it is the same price as the 5850.

    I decided on this combo for the heatsink discount:

    Looking at the 460, either the 1gig or the 768, haven't decided yet. My only concern with this is if in the future I were to want to do dual vid cards I couldn't with an nvidia, with no crossfire or sli. It may be a moot point, if by the time I need more power the dual cards might not be more economical than a new card.

    It depends. If you really want SLI in the future then change you system so that it will be compatible in the future. GTX 460 in SLI is a really popular thing at the moment of you over-clock both cards.( which is their good point). An SLI or crossfire board can be had for £65 in the UK. As for the PSU 650 or 700 should be fine. Id go for the 700watts for added security though. If you do get a GTX 460 get the 1gb version but you need to over clock it to get the full value from the card.

    Oh! I forgot that the Crosshair IV Formula does not support SLI. I suggest moving ahead with the HD 5850 then.

    5850, And with the correct power supply up to 3 of them on that cross-hair IV board.

    Ah, I'm glad I asked. I'll look into 5850's, probably get one and then if I need to crossfire later on I'll get more.

    Under full load a single GTX 460 1gb can peak at 307w

    Advertised GeForce GTX 460 TDP = 150W (768MB) 160W (1024MB)
    System in IDLE = 178W
    System Wattage with GPU in FULL Stress = 307W
    Difference (GPU load) = 129 W
    Add average IDLE wattage ~ 25W
    Subjective obtained GPU power consumption = ~ 154 Watts

    650w psu's are only the bare minimum required for a 460 in sli.

    Add a 2nd card in there in sli with both running full load and you're pushing it.
    Consider the Phenom II x6 is 140w, plus mb and peripherals, and any overclocking that may be done to the cards/processor, and 650w is just not enough to really play with. Granted, the 307w figure is worst case scenario, and not what will be seen during normal usage, though I consistently fold on gpugrid and folding@home with 100% load to my GTX 460's.

    edit: Correct me if I am wrong in my thinking here please.

    Seasonic 650w is just a good powersupply.

    I have to agree, he's talking about a 5850 and a possible crossfire in the future. 650 is on the low side. But I wouldnt get anything larger than 750-800 watts. Leave a little room for full load usages imo.

    The PSU is where in the past I have always cheaped out, but I figure with buying this much expensive hardware I'd hate to have a bad PSU fry it all. Here's what I'm looking at http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006
    Unless I dont understand, and the promo discount is already factored into the price, its $70 after rebate.

    So 750watts should be enough for two 5850s in crossfire?

    I am a bit confused about crossfire, do the cards have to be identical in chipset and brand? or can u crossfire cards that are identical chipsets and different brands?

    The only real big question left is which 5850 to get, the differences I see in cost seem to be based on the cooling that they use, is this an easily overclocked card? or would I be better off leaving it untouched and getting a cheap brand?

    Wait what, thats not a quote!

    I'd prefer Saphire, but meh they're all the same card. Cheapest one is best IMO.

    No...

    I have the Asus EAH 5850's CU with Votage Tweak and have them clocked to 915/1205 @ 1.196v so the OC is great, but they are not the coolest running cards, so you need to have good ventilation to OC them.
    BTW the load draw is 180W at stock settings you can add another 25- 40w for OC'ing

    You may also consider http://www.newegg.com/Product/Product.aspx?Item=N82E16817121068&cm_re=kingwin_1000w-_-17-121-068-_-Product. It isn't Gold certified like the Seasonic x-650, but it is fully modular, and has all the room you would need for future upgrades. The Corsair 750TX is an excellent supply, and there are rarely any bad things said about them, but for myself I chose the Kingwin and I couldn't be happier. The price was also just right for me.

    Choosing the right power supply for your applications can be a headache, but both the Corsair 750TX and the Kingwin LZ-1000 are excellent, and either will get the job done.
