http://users.bigpond.net.au/cpuburn/, u guys can try this prog n see if it can make ur cpu burn! burn baby burn!!! maybe not if u do post the results here.

Cinebench - "Especially a system’s CPU and the OpenGL capabilities of its graphics card are put through their paces (even multiprocessor systems with up to 16 dedicated CPUs or processor cores)."

256mb Nvidia 7800GTX

512mb ATi Radeon X1900XTX

U need to use the same GC for both PCs to run that benchmark as a comparison between the 2 systems.

irenic, the cpu may render it but the gpu still has to feed it instructions right (maybe wrong)?

Anyway if u switch the AMD's 7800 to the 1900 i think the difference for time to render will be less between the 2 systems.

Well try it out of u have the time.

irenic, 2 secs less is not much of a difference

Off topic a bit but I thought u guys might find it interesting:
