I saw the GTX 660 Ti can outperform GXT 580, but it doesn't matter to me because "Miracle of Kepler". Now I have one question, is GTX 650 Ti can outperform GTX 560 Ti?
You must be thinking of the GTX-
660Ti. The lowest level NVIDIA
GTX in the 6XX series is the GTX-660Ti which just came out.
There is no such thing as a desktop GT-650. There's a GT-640 and a GT-650
M, but no GT-650.
Anyway, if you're asking if the GTX-660Ti can outperform the GTX-560Ti, then yes, it can. The GTX-660Ti has even outperformed many of AMD's top-of-the-line cards. At $300 (not including tax and shipping) the GTX-660Ti is probably the best "bang for your buck" at the moment.
