Well Crysis did a hard freeze where you can't do anything (Caps Lock won't change) and I had to do a hard reset. TF2 and FO3 both had a display driver has stopped responding and crashed to desktop. I noticed that Crossfire isn't enabled and I'm trying to figure that out also. No my old NVIDIA card was not crashing. I put my jumpers on my T-Power i45 to CF configuration and I put the CF connectors on the cards. I couldn't find any BIOS settings to enable or disable CF and I can't find any in CCC to do the same.
