Not really a recommendation, just my considerations: That depends
on your budget, Mac Pro (5k$ in the U.S.) would probably serve
your needs for a long time ;-). I am running R 2.12.0 on a MacBook
Pro, 2.4 Dual Core with (only) 2G ram, together with (paid)
TextMate as editor, and Sweave. 2G ram is few! And I noted
remarkable improvements whan I was lucky to use a MBP Intel Core
i5 for a couple of days. Whatever processor and memory, I like the
easy interplay between R and the Unix environment (things like
passing shell commands from R to my system or other interpreters),
easy graphics etc.
If that helps a bit ...
