Architect workstation pc

Hello, 

I am an architect form Serbia, I need to get a new rig. machine that will be good for my type of work but also good for gaming. I do a lot of rendering ( 3dsMax + Vray, Photoshop and other adobe programs, AutoCAD, Rhino) , great need for space and also to be safe, I'm currently working on two screens but I would gladly have one more. My budget is around 3000 $.  

Thanks in advance for any advice! 

Im tired so Im going to be short with what you should look at. Your low price option would be an amd am3 like 8350, and one of the new Nvidia 900 series cards would probably be good. But also if you like amd there is the r9 series cards. If you want to spend all 3000 because god damn is it expensive there is intel's new x99 socket. x99 is like a super computer, lots of cores, lots of overclocking ability, and lots of freaking threads.
