I know I don't really need to upgrade, but I'm considering it anyways. I have a DS3 and a 6400 I'm thinking about getting a 680i and another GTS, and eventually a 6600. My 6400 is running at 3.2 right now, and I can't get it any higher. This DS3, I'm stuck using the F7 bios because if I overclock I get very poor performance, not to mention my NB heastsink is around 60c. Also, does anyone know if the Scythe Infinity will fit on the EVGA 680i? I know that alot of ppl have been complaining about the 680i, but I've built a ton of systems with this board, and I haven't had a single issue with it, so I'm not worried about having any problems. Suggestions?
