Should I keep?

Hi,

I have installed Vista b2 on one of my Desktops (its quite a decent set-up,
1GB Ram, Ati radeon 9800se) but it has only one HDD, nt massive so Vista is
my only OS on it.

With b2 being pretty slow, and me being me (lol), I thought maybe installing
XP was wise so I can take advantage of my specs with decent games like FEAR
and PREY etc... since having Vista a while now. Or should I keep it
installed to keep the new features such as parent controls (especially event
logs), and new file system lol?

Has any of you actually kept Vista installed since beta testing?
