I just bought a gtx 650 ti boost back in December, and I'm more than impressed with its performance. (snatched it up for $145) But I'm going to be upgrading again this summer, and I started making plans. I see other 650 ti boost's selling between $100 to$350 (new) on eBay, which is pretty much the only place I can find them available. I don't just want to put my card back in its box like I never used it when I upgrade and I plan to sli, but my question is should I buy another single card solution for around the price that a new ti boost will go for over summer, or is it fee sable to squeeze enough performance to beat a single card solution for near the same price.( since im upgrading Ill have a better case and a bigger psu, but I want to reuse as much as possible)
