xp -> vista RAC

Very simple question, how will my RAC be affected going from xp to vista x64? I can either use xp pro x64 or vista x64 business (I have both already). I've seen benchmarks showing 64 bit crysis is something like 15-20% faster, and I know that some boinc projects are significantly faster on 64 bit. I don't really care about DX10 at the moment.

Any advice would be helpful

I know there is a specific optimization available for the 64 bit XP and 64 bit Vista too.

However I have not seen any assessments of the penalty/gain experienced by conversion from XP to Vista in SETI yet. You may have the opportunity to be our test case

I've been looking over the stats and FPU seems to be the most reliable among different crunching rigs, based on those numbers I would be inclined to say that Vista is in fact a better cruncher than XP. I don't have an opinion on X86 vs. X64

Interesting, I thought that vista would be more efficient, but the system processes constantly using 1-5% cpu worried me a little. Looks like I'll go back to vista this weekend.
