I concur with seachnasaigh , With careful shopping you can get a very powerful system for a lot less money :D

Recycled HP workstation with no memory or cpus, posersupply and,purchased 2 x5670 cpus, 48 gig ECC memory, hard drive and various small items for a total cost of around 500 USD

Side benefit is no system crashes in two years

People that know everything by definition can not learn anything
