This review of quad titans has bar graphs showing a host of different gpu's from 7870's and 660's all the way up to 7990, 690, 680sli, and multiple titans. It seems like a good way to get an idea of single and dual setups and overall performance scale even outside of the crazy expensive multiple titan setups. us.Hardware.nfo: Nvidia GeForce GTX Titan 3-way/4-way SLI review incl. 5760x1080 and frametimes According to that review, a single 680 at 1080p seems capable of hitting 120fps on unmodded skyrim, and 118fps at medium setting on BF3. . Some newer games like hitman and farcry3 have much lower numbers. Whether due to more demanding graphics or poorer optimization idk. I'm curious what modded with much greater graphics eyecandy skyrim and some of the most demanding modern mmo's numbers would be. Also notably absent is the newest tomb raider but I don't think that was out when the testing was done. According to the review, single titan at 1080p , BF3 ultra 4x AA = 100.7 fps, enough for 100hz lightboost mode. Tweaking the settings down some would hit 120fps though since a single 680 at medium hits it. So probably "high" setting rather than medium or ultra would push you over 120fps. Farcry3 doesn't get over 80fps on ultra even with the beefiest gpus/combos. A single 680 and greater seem to hit near/at 100fps though. I wish there were more games on that review but it might give some idea anyway.
