If youre getting a similar processor (I suggest 2500k/2600k) and maybe a NVIDIA 580, dual 570, some AMD 7xxx card( all better than my card, also pulls more power), you can get away with a 600W if the PSU is a quality one. I'd get a 650W if I were you.
Even most GTX 570 / 580 systems only average at ~500-520W total power draw.
My old GTX 460 SLI OC rig (with a Phenom X6 1055T) didnt pull more than ~500....
However, these figures are measured ingame. You probably ran Prime + Furmark or something?.. But even then I can't imagine that system to pull anything above 400W.
Anyway, if we're going by reality which is ingame load, a good 520-550W PSU would easily
be enough for a GTX 580 build, I know for a fact and has been proven numerous times.
However, with a budget of 2000$ and the intention to max BF3 with the best possible gaming experience (60+ fps) I'd be looking at two GTX 580's in SLI rather than a single GTX 580 to be honest..
Found some reviews on the subject:Computerbase
Thats full system power consumption including the graphics card (GTX 580) as well as CPU and rest of the system
... in reality it wont even come close to 500W... so your 475W measurement with a GTX 460 must be WAY off.Edited by toX0rz - 12/20/11 at 12:09am
