Come on. Those programs alone are going to set you back the best part of $5k or so, and your worried about a few hundred dollars?
Your requirements are at the upper-end of necessary hardware, and unfortunately for you, simple economics dictates that such a computer will also be at the upper-end of the pricing scale.
