[R] best quad core configuration?

I am purchasing a quad-core 64-bit system. My proposed configuration is an intel core duo quad with 8Gb memory and an ubuntu OS. I'm choosing ubunto because I have good local support, but it doesn't seem as well supported as debian for R. Will ubuntu limit me in any significant way? I have noticed a bias towards AMD machines among R users - are there compelling reasons to go with an equivalent AMD system instead? Will I be able to use amd64 binaries on this system, or would I have to compile everything myself? Would it difficult to install Intel MKL 10.0 BLAS and LAPACK libraries on this machine? Would it be difficult to run both 32-bit and 64-bit versions of R on this machine? The most computationally-intensive thing I will be using the machine for is large MCMC simulations, probably using multiple instances of LinBUGS. Any advice on configuring by machine for maximum speed for these simulations?
