We only have a very short time with this pair of X1950 cards as it seems there is a shortage of media samples. Some tests ran, and also placed them on the messy desk:

New Driver:

Intel Core 2 Duo X6800 2.93GHz
2 GB GSKill PC8500 Dual Chanel Memory
SilverStone ST75ZF Power Supply
X1950 in Cross-Fire & Single Configuration

Pretty Cards on a Messy Desk:

Having Problems overclocking in CrossFire mode with current software and ATi
rep told me that they don’t support media in overclocking their cards
what a pity, as you can see default clocks on GPUs, bumped up Conroe to 4.9GHz
and easily 18K+ 3D Mark 05.
