My gaming computer

[spel565]

What is the slowest component of the computer im going to build? What quality can i play crysis/dirt2/bfbc2/etc. on with eyefinity 1920x1080x3... fps? Price/performance? If i want to play with eyefinity which component is then the weakest, 2x1gb vram enought?

Gpu: 5870 1gb - crossfire 16x/16x
Cpu: i7 920
Moderboard: rampage ii gene
ram: 6-12gb 1600Mhz
Psu: corsair 850w or 750 if that is enought.
screen: 22' x 3
hdd: regular, a couple of tb

You won't need 12 GB of RAM.

I'd step up to the i7-930, as it's basically the same price for a better CPU.

Trade the board for a Gigabyte GA-X58A-UD3R for more future proofing.

Two 5870s is kinda of a waste. It'll cost you $800 when you could get a 5970 (technically the same thing) and only spend $700.

As far as FPS, I don't know. I doubt you'll get playable rates with Crysis, as a single 5870 barely gets that at 1920x1080. Crossfire scales something like 70%, but you're tripling your resolution. The other games should be fine though.

As far as a bottleneck, it will always be the GPU for gaming.

I already have a gpu/motherboard btw, lol.
Question is 5870 in crossfire enought for playable fps rates with eyefinity, dirt2 f.ex.?

Yes. I should add that Crysis is just barely not playable (around 28 FPS average, with 10 FPS at min.) with an Eyefinity setup.

Your build will be GPU bound. VRAM will be highly limited, you're better off with 2 5870 2gb cards, though even then crysis at that rez...

settings? gpu?

I'm using the 5970 as reference, as it's two 5870 GPUs on a single card. Settings were maxed out.

5870 crossfire is better then 5970? And then its playable at gamer which im satisfied with. Then i should be able to play games like dirt2 dx11 maxed out with eyefinity?

The 5870 CF and 5970 are pretty much the same thing. The 5970 is made by placing two 5870 cores on a single card. The cores are usually downclocked slightly on the 5970, but essenitally it's the same thing.

Assuming you turn all of the settings up to the maximum, the only game you will have noticeable slow downs in is Crysis. Everything else will be fine.
