Thanks for the replies, and sorry for the delay. I've been patiently waiting for the store here to get some more of these cards in stock. (I can get them elsewhere, but this one place in Calgary has them far less than anyone).

I ran the game in single monitor mode, and it also froze completely after running F.E.A.R. for about 5-10 minutes. I didn't see many flashes of green or anything, although I did notice that my card temps are actually hitting as high as 70 C, I don't know if thats a seriously high temperature.

Once the cards come back in stock, I'll replace this one, and buy a second for SLI. but I'm going to make sure I have a high flow 80mm fan right next to them to help keep things cool.
