i agree with everyone that said to build your own...it's not that hard to do, just keep grounding yourself so no static charge is happening.
i build my own. the last one cost me $1300 and would have cost around $2000 at a store. you definately save money. and you also get what parts (mobo, chip, graphic card, etc)  you want instead of buying "what comes as a package"...which is usually a big waste of money in the long run.

Comitted to excellence through art.
