Johnny, rebates are not guarenteed. They really do not matter in the long run. and if it is damaged, then you file a report against them. Geez. And why would I pay more for a less powerful card that may or may not have a rebate that works. Heck, my case did not even come with the forms to retrive the rebate. that was an extra $10 down the drain.
I want a older card. 5870 will do what I want and I will get it. If I were to get a 6870, then I might as well go for a 7870 as the 6870 is old too. 7870 might as well go to a 670. Over budget. Goes quick. In case you did not notice (and no offense intended), but we spent 2 pages determining what GPU I wanted, and the 5870 wins.
As for vista, I think so too. might have to rearrange my room, but it will fit I think.
