So my computer is a total piece of shit with an old P4 1.4 GHZ cpu. Recently I got a 2.6HT P4 from my buddy and threw that thing in. The only problem is it seems like it's only giving me a tiny bit of performace increase, not only in windows but in games as well. I used to play Rome total war on my p4 1.4 and it would run like a slide show on the really big battles, but even with my new cpu it runs pretty much the same way. Is there something limiting my cpu, is my MOBO restricting it or something because the mobo is old and shitty stock mobo? Do I need a driver, what's the deal here?
