anyone with an quad core, 4 gigs ram, and an decent graphics card can play any game with decent fps. most games don't even use more than 2 cores and unless PS2 is programmed as an 64bit program than its not even gonna use more than 2-4 gigs ram. yarr
myself only have an AMD 64 x2 4200, 2 gigs ddr2, and an HD 5770 1gig. got new motherboard recently so only need is new ram and cpu
