I'm trying to find out what kind of performance gain to expect from a Tri SLI GTX580 set up vs a Tri SLI GTX570 set up. The difference in cost is about ~£400.
Essentially, what I'm trying to do is push out Crysis etc (CRYSIS 2 when it comes out ) with blistering frame rates; regardless of price (~£3800 w/ GTX570, ~£4200 w/ GTX580).

So guys, can anyone shed any light on this.
FTR, I'm doing a google too, but I can only find Dual-SLI set up benchmarks...

My first question is, why? Anything above about 30FPS is just about overkill (just about, as it isn't all that simple http://www.100fps.co..._humans_see.htm)

I run Crysis, with a mod to enhance some of the graphics, at a smooth framerate, between 25 and 35 FPS, everything maxed, resolution of 1280x1024, with a single GeForce GTX 465 Superclocked.

Unless you are playing at some extreme resolution, and/or multiple monitors, do you need to do a triple SLI with 570s or 580s? Either one of those would most likely work fine for any average resolution, and dual SLI for most after that....

3DVision. this and the demand of newer games, plus i intend to run them in fhd (1920 x 1080) with fsaa etc etc. Dual is for 3D vision in most cases, Tri is for the case of Crysis 2 and newer 3D vision games that may surface - ie future proofing.

I can go down to dual, and keep the third out for when i need it i suppose.

Ah, ok, well that makes a little more sense then

[pryogene]

It was either that, or dual HD6970's, which don't pack the same power as dual GTX570's, so even then I'm getting a much weaker system. Plus no 3D etc.

So to the real question, 570's or 580's. In most games I can't find benchmarks with a massive difference in SLI, but in some it's phenomonal.

I suppose I would say, if you can afford it, go with the 580's.
