If you were just starting like me, and had $600.00 to dump in a pit (Like me). Also, like me, you already had a case, hard drive, Wireless, GPS and Software (again, like me) what would you buy?

Monitor:
Board/Proc:
Memory:
Power Supply:

Give my your suggestions! I'm looking to buy in the next day or 2 and already have a good idea laid out.. Just looking to see what some of you would do differently...
