off topic: doc holliday, by any chance were you in a gaming community called GlobalFortressCommunity?
on topic: you have an 8800gt, i dont see any need to oc the videocard, you should be able to run any game out on medium settings or greater with more there 80fps.
edit: i just took a look @ your other post with your spec is in it... my advice would be to look into getting xp on the machine. it looks like it should run vista just fine. but for the way your saying that you would like to use this machine xp > vista. it should run a lot quicker and smoother with xp. but before you take the plunge and change to xp, MAKE SURE YOUR HARDWARE IS COMPATIBLE WITH XP.
