I love ATI I really do, I loved the 5850's and 5870's I had a couple of each. I probably have some of the most minimalistic computer usage and habits of everyone here.
I GAME, mostly BC2 and L4D, some bioshock 2 and dirt2 and maybe some mw2 thrown in. I watch movies sometimes and listen to alot of music. I still have loads of issues.

All I am gonna say is look at my sig... ATI DRIVERS SUCK COMPLETELY SUCK, the issues DECREASE with one card but once you go crossfire, F-IT nothing but HEADACHES, SAD TO SAY.

I went 470 SLI and never looked back and never had an issue. Now that i am back on one card I would use a single 5870 again possibly, I am very happy with a single 470 however.

Still incredibly turned off ATI with recent drivers.
