I'm building a bleeding-edge Workstation to be used for Photoshop and Adobe Premiere. The plan is to design this machine to last 4+ years without major upgrades, this means that price isn't really a major constraint (aiming for $6-7k per machine). I'll be working with PS files between 1-2GB and Uncompressed HD video with Premiere. Both of these apps are designed to work well in multi-proc environments. I'm currently planning on building the system with the Intel QX6700 on the Nvidia 680i platform.
I'm very curious about workstation and server class motherboards for the Dual and Quad core Xeon procs, especialy ones where I can use more than 1 physical processor, but it is hard to find information comparing thier performance compared to what I'll be seeing on the 680i with the Quad Core type procs, especially once its tuned and OC'ed. Any suggestions where to find data/reviews like that? Anyone doing anything like this out there?
