Ok so i've got a decent pc, and reasonably chuffed with it, a 4850 which does all i can ask of, and a e2180 clocked at 2.6ghz.. am i likely to see a huge increase by clocking it to say 3ghz?... also i'm still running on crappy ide hard drives, would i see a nice improvement on general running if i got some satas?.. (like would it be worth the hassle of re-installing everything for it, or should i wait for windows 7?.. )
