My 9800GTX+ (eVGA, 512MB) works great. No problems with a 512MB 9800GT in the machine I just built either. (What exactly is the problem with some 512MB cards?)
Be cautious of XP and AHCI on the Rev. 1.1 version of the UD3P- chances are if you get it from newegg that's the version you'll get.
I simply could not get XP-64 to load with AHCI turned on, and yes, of course with the proper AHCI drivers. It installed fine with AHCI turned off. I hacked the drivers the same as I've done countless other times, even with the older UD3P. But on this rig, XP-64 failed every time, with a message 'Could not load Operating System'. Turn AHCI off, and it boots fine.
Then I tried the 'old fashioned method', IE: the way it's actually supposed to be done, and installed the AHCI drivers with a floppy disk at the F6 prompt while reinstalling XP-64. The drivers loaded, the OS installed, but same thing- on restart the system couldn't load XP-64 so long as AHCI was enabled.
I didn't try the 32 bit version of XP.
Vista, both 32 and 64bit Ultimate both worked fine with AHCI enabled at install. It may just be a fluke of just this board. It might be some combo of incompatibility with XP and the on board TPM security chip (I forget if the v1 board had that or not) or it may just be XP-64 bit. In any case, I'd be wary that this board may have evolved past the era of reliable XP backward-compatibility. Might be time to either choke on Vista, or just wait for Windoze 7.
