i am looking for either update my system and go with a pci board and up my processor to a 3.0 duel. or get an AGP radeon 3850 card. i'm not sure if that card will boost my gaming by atleast 40% better, or would it be better to get a new system with a 9800 nvidia and upgrade to three gigs of ram. i am willing to pay for either. Im just not sure on how much of an impact the new card will make.
