I'm new to this site and I'm wantint to upgrade my graphis card but I dont really know which one to buy..I have a sony vaio desktop rcv-rs 312 with a 2.4ghz p4,1gb of ram,and a 80gb hd..Everything is stock except for the ram which I upgraded last year from 256 to 1gb..It has the intel extreme graphics with 64mb shared memory,,What would be the best card to get for under 150 bucks that would be a good upgrade..Any help would be appreciated..As I am very lost in this area of the upgrading deal..Oh by the way its used mainly for just playing a few of the older games and watching some movies..thanks again
