My 5870 is treating me just fine. Glad to be supporting the Red team. Don't get me wrong, I own an 8800GTX, 2 GTX 260's, and I have had a 4830, 4850, 4870, 4890, and now the beast! 5870 FTW!
I just hope they are able to turn things around on the CPU side, I am awaiting some good reception with the Phenom II X6's and hopefully Bulldozer as well.
