It can be faster in terms of having a faster workflow.
But that all depends on how you’re approaching things on Linux.
XFree86 (graphical subsystem used for almost every Linux distribution) is generally slower (and has less features) than (the graphical subsystem in) XP.
(fortunately that will change with the new freedesktop X server, which also features translucent windows, drop shadows and the ability to setup a custom compositing manager -> very cool stuff - see this site for technical screenshots of this new server)
In terms of display speed: If you’re using an NVIDIA video card you’re lucky because you’ll be able to use the official NVIDIA drivers (see NV website) which is known to be one of the fastest driver implementations for XFree86.
Dunno about other cards but haven’t heard many good things about them.
Latest NVIDIA driver seems to be very stable too.
is it more stable?
Depends.
An unstable graphics driver can make XFree86 unstable as well, and make it crash or lock up, altough it will usually (often) not lock up or crash the whole system (like Windows) and you can easily restart XFree86 (if you know what you’re doing).
Linux itself has almost never crashed or locked up on my system (only time it happened was when I tried an unstable beta version of the upcoming 2.6 kernel) so yeah, I think that part of the OS (ie. the kernel) is quite stable.
i have games and things, is there like a windows emulator i can use to easily run them from linux? if i do make the switch, i dont want to be changing between OS’s, i wanna stick to linux.
There’s Wine and Winex; these are no emulators, instead they’re just implementing the Windows API’s.
Be prepared to switch or fiddle a lot with different Wine(x) settings for each game, demo or other Windows program you’d like to run.
Fortunately, more and more games (only the better ones tho) are coming to Linux, including Doom3
where can i find a basic low down on the different versions?

Oh, and don’t expect to stick with Linux in one day; you most probably won’t
(though there are some exceptions out there)
