No, SLI is actually pretty good... if a game and the driver supports it. And to elaborate, I mean that 70-75% of the games I play really don't need SLI to be playable on maximum 1920x1200 settings as at 60 fps as most PC games are lead developed on consoles. It's only the major releases like Tomb Raider, BioShock Infinite, Battlefield 3, Crysis 3 and Metro: Last Light that get proper SLI support but even then not all of those need SLI to run at 60 fps maxed out at 1920x1200. Maybe if you're a 'twitch' online gamer who prefers 120+ fps then SLI is a worthwhile investment. SLI is certainly better than CFX in my view. I got a second GTX 680 more out of curiosity than anything else as I wanted to try it for the first time and see how it compared with my HD 5870 CFX experience. On reflection, it was nice to have but most of the time my second GTX 680 is wasted (although it is nice to have lower temperatures due to each GPU sharing 50% of the workload in supported games).
