For you to be getting such high CPU usage from the GPU client you must be using XP, running it on Vista it would use much less. Under Vista 64, I get about 6 to 8% cpu usage on my quad. XP users generaly need a full CPU core per GPU client...lol yeah, its pretty disheartening when you see the puny scores the cpus are getting
CPU1 400 :dots:
Even using the GPU client, my quad @2.93 is getting ~2000 PPD running the SMP client...
