If you have to purchase a whole new system for this, than $1500 isn't all that great. You're going to need good fast storage, RAM, lots of RAM, and good processing horsepower. How large are the files you are going to be working with? In my opinion, I'd spend the money on more fast local storage, and RAM. A decent Quad from Intel or Hex/Octo core from AMD would suffice as those Adobe products are fairly good multi-threaders. A Titan for that kind of stuff is rather silly. If you do this type of work for a living, I'd highly suggest a Quadro, or similar workstation card. But one of those could easily swallow up your budget, and more.
