I want to do 3D stuff too. And I thought the CPU and GPU have to sorta match speed, to avoid bottlenecking. will the bottlenecking be CPU to GPU or GPU to CPU? either way, "an army marches at the speed of the slowest unit", so if 1 3.06 CPU will be able to keep up with 3 SLI, then all is good. I just want to see some numeric relation. Like http://ark.intel.com/Product.aspx?id=47933 shows what the CPU can do. But I don't know the equivalent in 3 SLI to compare the numbers
I'm not sure a 4ghz cpu will keep up with 3 GTX580...
From Tom's article:
"Intel’s Core i7-980X is the most powerful CPU in our arsenal, yet even it isn’t strong enough to provide optimal gaming results when paired with more than a single GTX 480. We thus ditched its powerful boxed cooler and used an even larger unit as we clocked it to 4.00 GHz."
Why? What is the limitation in CPU that will choke the 3 GTX580? There is a numeric value that is the CPU limit and there is a numeric value that is the 3 GTX580 limit. and these values can/should be compared "apples to apples". Where can I find such numbers?
Don't wast your money on extreme performance you ain't gonna use. Instead of trying to get extreme fps which are far too high for the human eye try going fr great peripherals and such which actually do improve both your gameplay and intensify the experience. With 4k here's what I would do:
corsair 700d and get a powdercoat on it: 700usd max
decent LC: 600
3X dell 22": 800
thats around 2k now for the rest:
intel i7 2600K(coming out on 5th of jan): 300
p67 mobo: not a clue
8/16gb of ram: 150-300
psu: xfx 850: 130
GPU: X2 570gtx
Storage: 4x momentus xt 250gb/500gb running of a raid card.: 400
razer lycosa: 70
razer deathadder: 50
razer destructor: 40
xonar sense + pc 350 bundle: 200-300
I don't have a clue what that adds up to but that's the most exclusive build I can think of. If the price is too high there are numerous cutbacks to make. In terms of performance there's better, but in terms of best possible gaming experience this is the best there is.
