I just built a new PC (in sig) a few weeks ago, and as much as I love these video cards, I have been bumping into numerous driver issues and crashes. The only game that I rarely play that takes advantage of Crossfire is COD4, but that's about it. I'm thinking about either selling both these cards and getting a GTX 280 (cheap) or just selling one of my 4870s. I'm playing at 1920x1200, so I want the best possible solution, but I don't want to deal with any kind of multi-gpu solution.
