Ok i just spent a while reading everything. lol. And Whats the difference between a $120 MB with 32gb ram capacity and 2 pcie slots and a $180 Mb? just curious i dont know much, im a newbie

. if i do any OCing it will be to 4 ghz max because i dont want to ruin anything and i want to run games like Cod Mw3, and BFBC2, Crysis 2, Borderlands. I also have one question... why do i get so many lagspikes? in diablo 3 and mw2, on single player my frames go from 80-40, which LAGS HORRIBLy. its so frustrating and it feels like im 2 fps, i guess its a hiccup. If i havent mentioned already, i got a hd overclockable edition XFX 7770. do i really need to upgrade that on a single 20 something inch 1920x1080 monitor? My motherboard is GIGABYTE GA-MA78LMT-S2 AM3 760G and it beeps because of a broken sensor, which makes it underclock at "100"c. i think
No way am i keeping the current motherboard by the way.
