Do I upgrade from XP 32bit for new gaming rig?

[drunknmunkys]

I'm building a new computer. I've got Windows XP 32bit installed, and even though I don't have the cds anymore I have the key so I should be able to make a installation cd for my new hard drives. Here are my options:

Windows XP 32bit - 0$

Windows Vista 64 bit - 79$

Windows 7 RC - 0$

Basically, will I see enough improvement in my gaming experience to justify buying Vista 64bit over Windows 7 or XP?

New system specs:

Phenom II 720 AM3 system, 1920x1200 res. on 24in monitor (more details available if neccessary)

Thanks!

Use Windows 7 RC for now, and upgrade when it comes out.

Agreed, I wouldn't buy Vista with Windows 7 just round the corner.
