ASUS P6T WS/ i7/ windows7/ HD2 PCIX core and accel

[itguy]

Hello! I have recently bougth a new computer, I will post some of the setup.

ASUS P6T WS Professional, Socket-1366
Silver Power SP-SS620 620W PSU
Intel Core? i7 Quad Processor i7-950
Corsair H50 Hydro Series CPU Kjøler
ASUS P6X58D-E, Socket-1366
Corsair XMS3 DDR3 1600MHz 12GB CL9
PowerColor Radeon HD 5750 1GB GDDR5 / PNY Quadro FX 580 512MB GDDR3 128-bit
Corsair SSD Force Series 2,5" 120GB
WD Caviar® Black 1TB 3,5", SATA 6Gb/s
Sony Optiarc DVD±RW burner AD-5260S

The mainbord has set the speed on the PCIX to AUTO, and not on 166 or 133. Should this matter?

I am using windows 7 64b, protools 9, and the core and accel card.

When I do a clean install, I get driver problems with the core card(This is because of the VGA driver), when I uninstall the driver to the grafics, I get the driver for the core card.

So either I have to choose between very annoying display, or no core card.
I have 2 grafic cards, tryed both off em, nothing is diffrent.

I will try to install Windows xp, to see if that solves the problem.

Anybody here who have anything that could help solve this problem? It would be AWSOME!
