Make 5 virtual browsers working from different IP addresses on one computer, Chinese preferred

Can the VNC on the server be as fast as the timestamp on the real computer? Is there a problem in generating a picture because the real computer has a video card that takes it on itself, and on a VNC server it is generated through video emulation? Do you want to try to make a program like a virtual machine under the Fedora. I need it to make sessions on the VNS under different users and that only a broker of fireworks is available in the session. There is no need for other programs. such as 5 such sessions and braves on one physical server with a powerful video card. Everyone is connected to a separate popup address (a physical separate network card) and a separate AIP address - this is I organize. The resources of a productive video card will be divided into 5. the project budget is 600 dollars to you at the moment. And somewhere the same will go to the iron and its setting. Can it be done for such money and how much time it takes?
