Hi Robert, Here's my 2 cents.
64-bit is a memory issue, not a speed issue per se. If a concern is increasing RAM (which is important in R since objects are stored in RAM), then you will want to get 64 bit if you plan on getting a computer with over 4GB RAM. I'm not sure about this (someone correct me if I'm wrong), but I think that windows has problems addressing that much RAM (surely the 64bit Vista is OK with it though... surely). Linux or Apple (the powermac) might be better bets if you're wanting to work with programs that use a lot of RAM. BTW, Intel does make 64 bit chips now. They use them in macs. As for speed, go with multicore processors with as much GHz as possible.
