What would you do in this situation?

[turtlez]

Needing to upgrade the computer.

• Graphic designer by trade (Photoshop, Illustrator, Indesign, Acroboat, Cinema4D, modo)
  
• Freelance Illustrator (Photoshop, Painter, modo, Zbrush)
  
• Hobbiest GoPro 2.7k 30fps video editor (Premier, After Effects)

• Don't want the AIO iMac because I am against having to upgrade a great screen each time I upgrade the computer and heating issues.
  
• I was reading up a lot about the new minis last night but not entirely convinced because of the GPU and heat issues.
  
• The current mini seems to be faster than the Current Mac Pro...
  
• Don't need portability

This pretty much points to a PC right? I mean all the software I use is multi platform and I can use Windows just fine.

Thoughts?
