Dont' waste your money on the 8600 mate, go for the 7900 series. i just upgraded from a 6800 to 7950 GT OC (512 mb) and it's made a incredible difference! FPS shot up from 30 to 55-65fps on SH4.My Comp. specs are P4 3.2 HT, 2 Gigs of ram, 7950 GT OC,OS Window Pro.I'm waiting for next Gen DX 10 cards to come out next year,besides there are no DX 10 games out and Vista needs to be refinded a bit
Save your money until next year
