Yea it kinda crashes on x64. Was able to get this info before it does though if its any help to you.
On PD945, 7950 GT 512MB oc edition but can't remember the clcok speed. Will try and find that again. Also the driver for Vista aren't brilliant at the moment.
I'll try and get it on the XP 32bit system I've got.
[EDIT]Got results from XP 32bit system. Much better. On a 6700XL 128MB

spat out an error for both...
