Thanks for all the solutions for the last problem, I finally decide not to buy PNY fx 5900 and wait for the R420 or NV 40. But I really want an upgrade now, from my geforce 2 mx 400. I have amd xp 2700+, pc2700 512mb ram kingston, Asus A7N8X, seagate ultra ata-100 120 gb, and a sound blaster audigy 2, should I get a 9000 pro or Ti 4200, and also in ti4200, should I choose the 64mb version?I have heard that they are really fast and can out perform the 128mb version.
