[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?

Thanks,

Alan Swanson
