Other parts of AC 8/9 will not.<BR /> As far as Athlon 64, there should not be any issues, ArchiCAD runs on AMD processors just as well as on Pentiums. I have been using AMD processors for the last circa 7-8 years. They always worked well for me. Also, AMD is cheaper and faster than comparable Pentiums (according to most reviews).
