Well i have a quad core intel extreme PC, and it just smokes- but running XP64 pro i find P7 to be VERY unstable- it crashes totally at random after deciding that whatever PZ3/cr2 im working on is unacceptable- then after a few days it forgets the taboo on that particular figure and i can use it again.

since this does not happen on my laptop with P7 and XP32 i can only assume it is the OS.  it's driving me friggin crazy
