I woul like to clock it higher than 4.4 to get max performance in a 25 man raid in world of Warcraft. At the moment I'm at 200+ fps in the open world but in a 25 man raid its running around 35-42 fps with settings on ultra and shadows turned off.
Turn down spell effects, zoom out. Trust me going higher on your CPU wont do much. Try overclocking your gpu some. More ram won't help.
