In order (and I think you mean xw6400 rather than wx6400).
1) No it was not a mistake. The Bulldozer CPUs are heavily optimised for multi-threaded server workloads and have proved to be less suitable for lightly-threaded user tasks than more conventional CPU architectures. I doubt you'd have seen any advantage over your twin Xeons.
2) The HP workstations usually come with workstation GPUs (ATI/AMD FireGL I believe). You should find that your CAD software is rather happier with this than it would be with a consumer graphics adaptor. The usual rule for monitors for CAD work is "bigger is better" though....
3) Nothing wrong with Sammy disks. I use 'em.
4) 8Gb should be adequate. Looks like it takes DDR2 667 (PC5300) memory, buffered and registered.
