Hahahahaha. No.
Remember, the gtx 480 overclocks well, too, it's much better than gtx 570 in this regard. And while gtx 560 ti overclocks pretty well, its nothing like the gtx 460 in that department.
But they're really for 2 different uses, anyway. A high end card like gtx 480 does better and better as details/resolution increases, while gtx 560 ti has a sweet spot in the 1680x1050 to 1920x1080 range. Heck, even my gtx 460-768 @ 905 core should be plenty for 1680x1050, right? Well, it's not. I can't play with any AA in DAO, and I'm stuck at medium settings in civ5 (and even then it hitches and jerks sometimes). What's gonna happen to me when bf3 and skyrim come out?
Plus, all those custom AA levels even on older games really bring cards to their knees. Even using 2xSSAA in nwn2 is a slideshow on my gtx 460 right now, with the new card I should be able to really crank up the details.
From looking at
TPU's gtx 560 ti launch review, gtx 480 is about 15% faster but also gets better as the details/resolution cranks up (as we'd expect).
I'll settle for good performance when that's all I need/want, but when my primary games are suffering and even more taxing ones are just around the corner I'll take the higher res. Besides, even without the $25 rebate, for $207 I can probably make money if the card ends up being too loud/hot.
