I have a 9600gt 1GB that I have been running for a year. This card works okay but I'm looking to upgrade to a Directx11 card. I'm kind of torn between the 7770 and the GTX 560. I know the 7770 uses less power and the downside is that it is 128bit. I was looking at the EVGA GTX 560 SC but I don't know if it is worth $129 AR. Should I wait until both these cards drop in the coming months? My price range is around $120. Also, my power supply is an XFX Core V2 450W.
The 560 is a faster card than the 7770, but not by too much. They both overclock very well too. A decent 7770 can go well beyond a stock 560 and maybe even almost as far as an overclocked 560 (128 bit bus versus similar 192 bit is not a big difference at this performance level, although the 192 bit bus is undeniably a decent advantage), but it probably won't catch up to an overclocked 560 in performance, although it will have a huge win in power efficiency.
