I'm really kicking myself if the 6570 card will do. It has: Memory Interface 128-bit Memory Type DDR3 Stream Processors 480 Long time ago I had a 4850 over AGP and it ran at about 48% to 62% at anytime during game play and everything could pretty much be on max. I guess the big question here is will the 6570 be enough or will I need something more? Also if there is much of a difference between 128-bit cards and 256-bit cards? As well as DDR3 memory vs GDDR3 / GDDR5.
