Improvement When running 64 bit OS.

[bigal40]

I just read These benchmarks of the amd 64 and the pentium on 64 bit linux. In alot of the tests when running the amd at 64 bit there was large improvement in the amd's running in a 32 bit enviorment and in a 64 bit enviorment. In one bench i think it was almost double(i forget which one). Do you think there will be this much improvement with Windows 64 bit when it comes out
