I have 2 working computers, one with an older AMD K6 2 @ 500mHz and a newer AMD 2400+.... both give me excellent performance with Poser and all my 3D programs. I believe they perform a bit faster than Intel as far as realtime clock speed and I am sticking with AMD chips. A good cooling fan is a plus since they do run a bit faster and hotter than Pentium. A good tip is to never skimp on your cooling fans no matter what chip you are using...a good cooling system is cheap insurance.
