Compare the raw power here:
GTX 650 Ti:http://www.game-debate.com/hardware/index.php?gid=1324&graphics=GeForce%20GTX%20650%20Ti%20EVGA%20SSC%202GB%20Edition
GTX 560 Ti:

The 560 indeed is a better card (I mentioned in my first post itself), its just that 1GB is not enough for FHD. more than 3/4th the VRAM will be used up just for display, what will the 560 Ti really do with ~250MB free?
Performance/power= GTX 650 Ti.
More power= 560 Ti.
Better for future gaming (not really, none of them are powerful enough)= GTX 650 Ti.
Better overall= 650 Ti.
Here's what I think about the 2. I'd buy a 560 Ti over 650 Ti, but won't upgrade a 560 Ti over 650 Ti
