I plan on putting Windows 64-bit on my rebuild and was wondering if Windows 7 64-bit RC1 might get better gaming results. I know there are benchmarks, but I was wondering if anyone has had any experience.

Of course there are issues with Windows 7's compatibility with certain programs... it's not even final release yet. Once it's released, and certain companies get their acts together and update their software accordingly, there will be absolutely no reason not to run 7.
Bottom line is this: The current 7 RC (that is, build 7100) runs faster than Vista, and roughly as fast as XP (slightly faster in some areas, slightly slower in others, but nothing huge), but you get plenty of features that make it worth not considering XP (DX11, preloading programs, handles 64-bit far better... XP64 is a joke).
So, grab yourself a copy of 7 when it comes out, install 64-bit, and in a year or 2 you might just upgrade to 6/8GB RAM and feel happy in the fact you don't have to change your OS when you do.
id just go with 7 its working fine for me with punkbuster for COD 5 plus its free for a little while but id buy it in october or soon after because that will be after they take all the bugs out (if any)
