As per performance, you can use all the tweeks you want if you dont do basic things, its no good. I use a good defragger and defragg before each session.; Spend the money, buy a GOOD defragger ( I use UltimateDefrag ) and consolidate files. Turn off EVERYTHING not needed; anti virus, spyware, ect. Ive tried Game Booster and was not happy with it. Another thing I do, which some will argue with, is to erase all files in the PREFETCH folder every few days. Go to TASKMANAGER and look over whats actually running on your computer. You might be surprised at the stuff that is not needed. Also, check your STARTUP folder, see what programs are running on startup that you can shut down. Beleive me, these simple things will give you boost you will notice.
