One of the first things i do after reinstalling my main rig, is to drop the pagefile size to 300mb (older software sometimes crash when pagefile is disablet)
Depending on what you use your computer for, 8 Gig might be enough to run without pagefile, i usually advise people to do so when running with a bit more. to keep a decent headroom for multitasking an so on.
Doesnt really matter if the system is overclocked or not, disabling the pagefile will force the system to store everything in ram, instead of swapping to the harddrive, which results in lower performance (SSD's have helped, but ram are still a ton faster then a SSD)
