So as of now I have a EVGA GTX 660 SC for about 2 and a half years now. My friend asked me if I wanted to buy his GPU which is a EVGA GTX 770 SC/ACX 2GB for $100. I'm kinda one of those budget Pc owners and I was planning on getting a 960 2Gb. His graphics card is 2 years old and he only played a few games on it which were Counter Strikes, Need For Speeds, and Grids. So overall not a lot of intensive games beside maybe Grid. Is this a good upgrade/deal?
