I have an AMD Athlon 2400+, 512 mb ram ddr, 120 gig hd, and a 256 mb ati 9550 graphics card. I ran 3rd Mark 2003 and I got a score of 2372. I saw other users getting 7000, 8000, on these forums. Is there something wrong? I've noticed poor performance in some games also...What do you suggest? Thanks a lot!
