Windows' scheduling is not the best....

I have an Athlon-64 3200+ here and can watch normal tv while the system is
completely loaded (playing my favorite online game) without problems. Under 
Linux, and the tv window is 300x200 small in this case. With a budget card of 
course (this is my test setup).

But I agree, I would not recommend a budget-only solution for a "production" 
system.
