Windows Vista - Is it worth it?

Hello all, I have a very powerful PC running Windows XP SP2, but I have recently heard news about Vista where you can have your own gamertag and play against 360 owners (even though I own a 360 already) but the graphic experience is also good, games like Halo 2 coming for Vista and that sound good. But it's also rumoured that Windows Vista doesn't play a lot of old games such as the previous generation games (e.g games that were released between 2002-2006), also I'm scared that my video, audio and other cards and drivers won't work with Windows Vista and if I install Vista I won't be able to re-install Windows XP SP2 again, my computer is ordered from Dell and has all those discs which install the drivers on my PC but I wouldn't if they were Windows Vista compatible or not, my friend has a genuine copy disc of Windows Vista, so I can install it if I want to, but I don't know if it's worth it, I've got a lot of good games and programs on my PC and I don't want to wreck my PC. Any suggestions anyone? As always, help is appreciated.

 

we've got several official vista threads. i'll request this be closed.

if you read the *thousands* of posts on this topic, you'll find the general consensus of those in the know is, "no, vista is not worth it."

 

Stick with what you have - many people having problems with Vista.

Do not think this would work - validation problems if used previously. Vista incorporates DRM and is user unfriendly.

Recently brought new computer and insisted on XP as the OS

 

Ok, I guess I better stick to Windows XP SP2 then, i'm happy with that anyways, thanks for your help guys.
