Just wondering if anyone has any opinions on the Sapphire 5870 Vapor-X Revision 2. I've seen alot of good and bad and it is so mixed I can't make my mind up if I want to just get one of these for now. Alot of horror stories of gray screens of death, crashing, being unstable at the 875 / 1250 factory OC, yet others are stable at 900 / 1300 OC. From what I'm seeing, it looks like you are either hit or miss with these cards and it's pretty much the luck of the draw on if you get a good one or bad one. Anyone have one of these, or have experience working with one?
