Thanks for the find on the CPU, I didn't realize it was QM and not just M.
As for the GPU, it's an ATI card, that the vendors (I believe HP, Dell and one other company are the 3 distributors for it) have to provide custom drivers for themselves. It's essentially the workstation equivalent of a low-mid range 5-monitor eyefinity card. The subvendor may change between cards, but the card itself is a standardized part from ATI.
