Hey guys, just looking for a bit of input here. I currently have an EVGA GTX 560 (256 bit) 2GB card that I'm wanting to upgrade. I'm thinking of getting the 660 ti, but the 192 bit memory bus has me worried. I've read several reviews on the 660 ti and it seems like it performs quite a bit better than my current gpu. What would you do in my situation? My CPU is an i5-3570k (stock), 8GB ram at 1333 mhz, Antec BP-550.
