The 560ti's in SLI are insanely fast, faster than both those offerings, and still around the same price as a 580.
You may notice as you go around looking at signitures in this forum the number of folk who are using 560ti's.
They also have massive Overclocking Headroom. Its hard to justify getting anything other than a pair of these.
Faster than 460s, with similar OC headroom, but certainly over here twice the price. I guess I was just so pleased to get a pair for the price I did recently, as I got 2 460s for the price of 1 560. If (longer term) money is no object, then I would choose a 570 for myself and then pick up another when the prices drop. Here's my thinking:
2 x 460s now = £200
2 x 560s now = £400
1 x 570 now = £280 - assuming they drop in price 50% over 18 months which is very roughly what the 460s did (guesswork I know), then:
- 1 x 570 later - £140 or £420 total
Put another way:
2 x 460s now = £200
2 x 570s in 18 months = £280
= Total spend only £80 more than buying 560s now, plus you have a pair of 18 month old 460s in SLI to sell on Ebay for £100, and a better rig long term.
Depends on if you need performance now, or can wait. 560s = performance now, 570s = performance later but at less overall £/fps, depending on if you buy one now and one later, or 460s now and a fresh pair of 570s later.
