Thanks! It is a super cool job, can be a major PITA though. And yeah, the rigs we use are pretty crazy, I've been upgraded 4 times in the past year because of some of the projects we've been working on. I would say the machine I'm on now, would be ehhhhh? between 18,000 to 25,000 dollars. Which might sound like a lot, but its far cheaper than the distributive network we used to use, farms and farms of blade servers. But in the past couple years, really high end workstations are starting to be able to do the same thing for less money. The requirements are no different than they were years ago ( though I'm only 27, and have only been in the business for 5 years now, so my experience with the older stuff is limited )
Here is our vendor for the workstations,

). In fact I liked their work so much, I bought a portable gaming tower off them
