Has anyone with an Asus Rampage Extreme II (I am running an i7 965 at 3.81 temp not an issue) had imterrmittent problems with the Catalyst driver when using twin Shapphire (or any make) Radeon HD4870 X2s linked. I was running fine until I made the hugh misstake of upgrading to the latestest drivers. Now CCC will only see one the cards, although GPU-Z sees all four GPUs. Now when I go to play say HL2, Episode 2, on Steam I get all the way to the initial start page for the game and everything freezes and the steam engine quits. Any thoughts? I have gone so far as to re-install the operating system, Vista Ultimate, at which time everything worked fine for 48 hours but now I have the same problem again.

Bottom line from day one, CrossfireX on this particular board has been driving me nuts and I am ready for a single Nvidia 295. If anyone has dealt with the same problem please tell me what you tweaked and by how much to get stabilty before I go nuts trying to figure this out.

THANKS IN ADVANCE!!
