well
someone here already reported it couldt be the 8 GB of ram.
the Ati in other card, could be some sort of driver incompatibility. what version of catalyst you're using Andy?
I remmeber the old 8.12 was targeted by some x64 users for not accepting anything over 4Gb of ram ( it would crash badly until the ram was removed ) others didnt report such a problem, so its hard to know.
