Dammit. Every game that tends to code a lot of PhysX into the game tend to nuke my Xfire'd 4870's. Overlord II is a good example...the game runs fine on all my friends with Nvidia based comps, but myself and others using ATI always get random crashes. More and more games are using it now too. Wish it wasn't such a bane to ATI.

Might be time to look at moving to a GTX275 or something...
