I want to use one computer to operate two computers

[aflaba]

I have two computers. One for playing and everyday stuff and one for data mining and that kind of stuff.

Is it possible to comfortably run both computers from one screen?

I have tried MaxiVista (one of the versions) and it allows me to do that, but not comfortably... I have to change the screen settings to what I want every time I start MaxiVista and because of that it kind of loses it's advantages.

Do you know of any software I can use to comfortably run two computers from one screen?
