All these Vista(in)capable machines are all very powerful PCs compared to my main PC (and its a crap PC). But, im achieving something (very similar) to this link below:

Im using an old generic GEforce 4MX 512Mb and a 2ghz celeron. However it is just as smooth when not too loaded down, like loads and loads of windows open.
Pff, I'm running the Ubuntu Feisty beta on my 500 mHz Celeron Compaq Presario from ages ago. It has integrated i810 Intel Extreme Graphics and so little RAM that it is smothering the page file before I'm logged in. It can run Desktop Effects, which uses Compiz, which is the same thing as Beryl there (Beryl is split from Compiz, they're merging again soon).www.youtube.com/watch?v=p0HLtNydndU&mode=related&search=

It doesn't run well on there but it certainly goes beyond my expectations by actually running at all. Transparent windows worked, bouncy windows worked :) A few parts (for example, the Alt+Tab menu) really chugged, but they ended up working out in the end. It wasn't fantastic to operate Compiz on such an old machine and lots of effects looked less pretty than they're meant to look, but it did not die from it and in some cases it even felt faster than usual... (Some things, like dragging windows, seemed more responsive).
It's not running Compiz now ( in fact, they changed Desktop Effects so I couldn't! :( ), but it is fun to say that it can!
