The above is a link to a site that compares HP's AMD and Intel workstations for graphic creation. FYI, AVID now sells HP workstations with either AMD or Intel processors for their professional video editing software.
If you absolutely must have the fastest machine you are in for perpetual disappointment. By the time you get your new computer home, there will probably be at least two or three faster processors out from both AMD and Intel. RAM is just as important as the processor speed and the video card is nearly as important.
My bargain basement HP desktop with an Athlon XP 4200+ Dual Core and my HP laptop with a AMD Turion 64 Dual Core both zip right through processing 10 and 20 Megabyte RAW photo files and the desktop does the same with DV. I haven't tried video editing on the laptop.
