Assuming you want a PC and don't want to revisit the PC vs Mac thread:
Have two discs so that you can have your scratch disc on a different drive.
A decent processor (avoid anything with celeron on it) check PassMark Software - CPU Benchmark Charts, i3,i5,i7 are nice.
Some RAM 3-4GB min.
Any computer with that spec will run your progs. If you have a better spec it will run them faster but cost more.
