I know the people that have responded already all said "NO!", but the 6870 I'm using now, I got for $80 off of Ebay and it works flawlessly and I bought it from an actual person, not a store. I did luck out though and the person was selling it where I live, so it didn't have to go through the shipping process, but I still think it would be okay. I actually just bought a second 6870 to Crossfire and it'll be here tomorrow. This one I also bought from an actual person and he has a really great rating, so we'll see how it goes. I'll comment back tomorrow after I get the card.
