Well, right now I use a HIS IceQ-II X800Pro card that runs pretty fine without any problems. I use the OMEGA drivers because they have proven to be more stable than the Catalyst. (Believe me, before I had THIS card I did not like the Omega-Drivers).
Best BIOS-Settings: If you have a BIOS "older" than the pre-release of 2.03 you have to set the AGP-HT-Link-Speed to 600MHz.
The best BIOS (from my point of view) is the Beta 2.03. You can use the HT-Link Speeds of 1GHz, 800Mhz, 800MHz without problems.
Other things you should check:
For reliability I enabled ECC and
You should use 4 memory modules, two at each CPU to get the maximum possible bandwidth. I'd suggest that you take PC3200 instead of PC2700 because the whole system will profit from the speed increase.
Add the /PAE switch to the boot.ini to enable NUMA-suppport.
I did never test any FASTER video card on that board (because I do not own a faster one) but I can't think of a reason why a X800XT PE should make any trouble.
If you will need more harddrive performance I'd suggest to upgrade to a 3Ware 9500S-8 hardware RAID controller and a few (at least 4) pretty fast harddrives.
Take a look at the Maxtor DiamondMax 10 with 16MB cache http://www.maxtor.com/portal/s...or/m...DiamondMax%2010
or think about several WD Raptors. Just 74GB each but if you have eight of them it should be enough.
Anything else, please?
