So GTX 660 Ti will have under $325 price tag, on stock clocks performance between 7950 and 7970, cards that go for $350 and $430 and above, and when overclocked performs marginally weaker than 7970 GHx Edition which goes around for $450 and up. Pray do tell me which AMD GPU with price tag of under $325 preforms near 7970 GHz Edition's level when overclocked? Because overclocked 7870 in most games performs between the GTX 580 level and the GTX 660 Ti on stock clock level.http://www.tweaktown.com/reviews/4 [...] ndex1.htmlhttp://www.tweaktown.com/articles/ [...] index.htmlhttp://www.techpowerup.com/reviews [...] us/31.htmlhttp://www.guru3d.com/articles_pag [...] ew,23.html[/citation]
I'm sorry that you actually take TweakTown's benches seriously.
An overclocked 7970 is roughly equal to an overclocked gtx 680 at 1080p, with the 7970 winning at any higher resolution. The same goes for the 7950 and the gtx 670. Anybody can post biased benches, but nothing compares to physically owning or having friends who own the GPUs to compare side by side.
