If you're on somewhat of a budget, the general rule of thumb about going
for last months fastest processor (as opposed to the one just released)
is probably a wise bet.  And you probably want 8-12GB ram if you can fit it.

The only real and not always obvious trick is if you can afford an SSD
(and afford to kill it and replace it every so often) doing your builds
there is a real big win.
