I just got a second gtx 770 and have put it into sli. I have about 60 mods including ENBs, hd textures installed onto skyrim. I only get 30-40fps outside. This seems really low to me. I have Nvidia CP set to Force alternate frame rendering 2. Also I just upgraded my motherboard and lost my fx-8120 4Ghz OC. Its running at stock now. How much of an impact is that overclock?
