My single 780 is giving me 40 FPS on high settings @ 5760x1080. I was wondering if there was a $5-600 SLI or CF option that would give me at least 60 FPS at that resolution at high-ultra settings. I can't afford to buy another 780 unless I sell my other PC and I'd rather not do that. I can take my 780 back though and get something else. Thanks.
