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. -- Tom Rini Mentor Graphics Corporation
