You could add $50 to your budget and look into something like this:

2 Intel Xeon Six Core CPUS, 10GB RAM and a Quadro 4000 graphics card with 2GB V-RAM. I think that would do what you want very well.
EDIT:
You would have to install an OS, but it has a key for Windows 7 Pro right on the machine. Just download a Windows 7 ISO and you are ready to go.
