It only sucks balls if...

A. User error

B. You got it running on a pc that wasn't built for it.

I got it running on 2 machines. The first is a Intel Pentium 4  Prescott 3.0GHz  with 2 gigs of ram and a 256mb ATI x850 video card. It runs ok but the processor sucks balls so it kinda makes vista suck balls. I get alot of CPU spikes.

The second machine is a 2.2 GHz Intel Core Duo with 1.5 gigs of ram and a ATI X1600 128MB
It runs awesome.
