Which one is better? I've seen a few threads about this but they were mostly about ddr3 ones but I'm talking about the Low Profile 512mb ddr2 128 bit cards. They're both around $60 on Newegg the gt 220 is 625 mhz with 48 stream processors and the 4650 is 600 mhz with 320 stream processors. Can either of these run Oblivion at ok settings smoothly? I know they're not great but they have to be better than an Intel G31\G33 GMA 3100. My computer is a Dell Inspiron 530s slimline model with a 2.4ghz core2duo 3gb ram 500gb HDD with PCI E x16 or something like that.
