Vue Supports dual processor/dual core and it will have a very significant impact on your rendering. I have a dual processor machine right now with 2 gig of RAM. If I was buying/building a machine now I would tend go with an AMD Dual core machine. The price/performance levels between the Intel and AMD machines are quite different so you would have to decide what the proper balance is for you. If you plan on keeping the machine for the next iteration of Windows (Vista), having a 64 bit machine may be an advantage.
