I have access to two PCs for my Poser work - an AMD K6 and a Pentium 2 machines. They have similar specifications, but the Pentium machine is much, much faster for Poser - both rendering and posing. I am about to buy a new PC and the choice is between a Pentium 3 and an AMD Athlon machine both with same speed processor (1GHz) and same memory (256 MB). Can anyone advice me on whether the Athlon will perform as well as the Pentium in this configuration? Many thanks for any help!
