hi. i know that the gtx 260 core 216 is an older card, but i was wondering if it would be worth getting 2 of them for $80. i know a guy that is selling 2 x gtx 260's (core 216) for $50 each, or $80 for the pair. should i grab em, or take a pass? if i were to get them i would put them in a SLI build with a athlon II x4 650, or a intel g630 build, with a 1tb HD, 4 gigs of ram, maybe 8 gigs, and im not sure about the psu. let me know what you think please. thanks
