wow, 2 days to go....this should be hilarious....i wouldn't be surprised if it's close to $400 by the time shipping is factored in, lol. Man, i've never understood some things about ebay and electronics. It seems like on every auction, the bidding price ends up going higher than the in-store price on most items, and if it isn't, then shipping is like $20 extra and you still end up paying more. Who's gonna pay $200 for an A64 3000+ when you can go to newegg and get it for $140 with free shipping? I have not once found a good deal, after shipping, on any piece of computer or electonics equipment.
Anyways, rich1, yeah, you can use just 1 card. I'm going to do that with my 6600GT, at least at first. If they get really cheap, i might grab another for an extra speed boos later down the road, but we'll have to see. Also, that other PCIe x16 slot functions as an x1 slot in non-sli mode. Oh, and you can go with non-matching cards, too, if you want to use them independently, for rendering separate screens.
