Well, I burned the ISO to a cd and apperantly the default mode of the nvidia choice is too much for my monitors as I get a screen mode out of range on both monitors I have hooked up to the 6800GT.
The first menu choice boots fine, but the 2nd one puts my monitors out of range. I have a Samsung SyncMaster 192N LCD and a NEC MultiSync LCD1700V hooked up and both use a 31-80 Khz and 56-75 Hz, and the nvidia selection tries to use a much higher number than either of these monitors can handle.
I tried hitting e on the boot menu on the second option, but didn't see anything I could edit that would not make the screenmode use a high frequency rate. Plus I'm thinking on going back to a single monitor setup.
I have noticed though when booting up the first option, after I try a few things it will suddenly quit responding. The mouse pointer moves, but nothing on the screen will change and one time a line striped down the middle of the screen. Happened once in the middle of one of the games, and once just as I quit another game. I don't know if it has anything to do with I am running a AMD64 3500+ cpu with 1 Gig dual channel memory.
Although I think this Motherboard may have a problem as I'm not getting the normal sounds you usually get when it boots up. The problem was my fault as I did something that may have killed that part. So as soon as I can replace the motherboard I'll try again and see if I still get that sudden lockup then.
