I am puchasing some computers for a design group using Solid Works as a 3D development tool along with Viz 5 as a rendering engine. We also use all the Adobe tools. My question is this. I was going to order the pentium 4 3.2 GHz EM64T processor. Will I gain any advantage (speed, useable life etc.) by spending an extra $550 to get the 3.6 GHz processor. The rest of the pertinent data is 2GB RAM 1MB L2 Cache 800MB front side bus.
