XP or Vista for Gaming

As some of you might know I might have to result to build my own gaming rig soon. Yes I know I haven't asked anything about hardware yet. I will soon.
I am planning to use my computer mostly for gaming with some high graphics. Planning to run FS9 FSX and other flight simulations. Will use it for basic daily use. I haven't thought of any more uses than that.
I would want high perfomence from it. Stable, reliable, little problems. I have heard Vista has little problems with networking and drivers so that will be an issue.
I am used to XP and trust it but I might need to move up to Vista soon enough.
What do you think I should use?
Thanks
