GTX 460 768MB SLI vs GTX 570 single

[gr0bda]

How do Galaxy GeForce GTX 460 768MB in SLI fares against gtx 570 or even 580 (not that I can afford that one anyway)
right now that gtx 460 can be had for $80 after rebate, that's $160 for sli vs ~$300 for 570

Compares the 1gb versions in sli, so a pair of 768 will be somewhat slower.

the performance would be close to the 570, although the lesser vram on each of the 460s (768 MB) would be a hindrance at high resolution & anti-aliasing. The $160 deal sounds pretty sweet.
