I wanted to get everybody's input on my dream machine config. The primary role of the machine will obviously be gaming, but I also do a lot of software development. I've got a pretty big budget, but it's not like money is no object or anything. 
Here is what I have so far. Please, pick it apart and tell me what I should be doing differently.
