personally I think $4500 is silly to spend on a pc that will probably be average in 12 months time. unless you are a millionaire...in that case get 2 and send me one...
haha yeah you will not have a problem with a budget like that but I would say you'd be better off lowering your budget for now so you can buy a great computer but with enough potential to upgrade parts as new parts are being released.
Both are too much though, Compman's selection is nice but it's like $5778 US not including any shipping or keyboard, mouse or speakers. Atleast Cryman's is about $4660.
