will my upgrades be sufficient?

o.o ps2 emulation works just fine on my computer actually. oh btw since i posted this thread i tryed castlevania lords of shadow 2 and the gameplay is fine,and the graphics are beautiful, im just having this oddball audio problem where it stutters with normal sound effects,but is perfectly fine with menu music and cutscenes. then i fiddled around with the settings abit and now it only stutters up when there is alot going on on the screen

as far as the cpu is concerned id be happy to upgrade it,the only real requirement i have is compatibility with my motherboard (gigabyte ga-m68mt-s2) and at the very least,a base clock of 3.6ghz like my current one
