I had very bad technical service with ati. Technical support is all the way in Canada and I had to wait 20+ minutes for a technician. My first 8500 that I bought from ubid worked my my amd system, but it didn't work in my p4 sytem. So I bought another 8500, but this one has 128mb memory. The second card I bought worked in my p4 sytem. (see sig). Just letting you guys know that if you need technical support from ATI, beware of your phone bills!
