Re:660ti sli vs 780 running 1080p?
Because the Titan is ~5% faster than the 780, you can make a very good estimation of your results by looking at Titan versus 660Ti SLI. http://www.legionhardware...force_gtx_titan,4.html
If the Titan is bested (barely) by the 660Ti SLI, you can be assured that a single 780 cannot beat the 660Ti in SLI for 1080p.
If you're looking at Surround resolutions, the answer may very well be different because of the RAM.
Basically 660Ti in SLI is better than a single 780, but 2 780s in SLI are insane fast.
