The thing is though that I've attempted to disable sli and that essentially does nothing, there may be a 5-10 fps difference at the very most but it's not something i notice.
additionally I do play planetside 2 quite a bit on the side and from what I've seen I'd essentially double my fps both min and avg in that game and I'd do way better in rome 2, a game i'd love to play if I could pass 60 fps, i know wow doesn't utilise multi core well, and never will because the game engine is stone age and they have no plans to upgrade it for the foreseeable future. But essentially where I'm comming from is, I play games that go single core performance > multicore, and those games probably wont change that due to how their engines work, (for WoW going beyond 660ti there are no real benefits fps wise)
So my question more or less is. With me having the money to afford a AIO 140mm rad, a case to acomodate it+the 4670k or 4770k am I going to see any improvements in CPU intensive games Assuming I reach an overclock of say 4.6 ghz on either of the before mentioned cpus
