I'm RMAing the 6870. It crashed on me today while playing Dragon Age origins. It is having stability issues. I am replacing it with a superclocked EVGA 470. My case has the cooling to support that card. RMA process is drama, 50 dollars restocking fee on the card. I'm kinda glad though. I am a huge EVGA fan, and I love their precision tool, and I wasn't really liking how I couldn't control the auto fan temps with CCC. Matter of fact, I kinda hate CCC. The 6870 was a great card though. It just started giving me some mediocre fps on Dragon Age Origins at 1080p, and crashing my whole system. I'm not sure if it is the current state of the drivers, or if I just got a dud card(my bet), but with the setup I got, DA:O should be at worst silky smooth, and certainly not crashing my computer.
So yah, dud card, I'm replacing it with a brand I trust, even though I have to add a space heater to my computer, lol. EVGA cards have lifetime warranties. With my 260, I have never, ever had a game crash, ever, and I have DA:O, a game that doesn't push half of the 6870, crashing me to restart on day 2, and NOT maintaining over 60fps consistantly, despite great case and GPU temps. Can't keep a broken card. :P RMAd.
