This spring I had to build a computer for a class I was in and decided to get an EVGA 012-P3-2066-KR GeForce GTX 560 Ti (Fermi) 448 Cores FTW GPU because it was in my price point and I liked the specs on it. This was before any of the 600 series were released and now I am wondering if it would be smarter to get another FTW and use SLI for about 250 or spend 100 more and get a 660TI?
