Windows vista 32 bit vs. Windows 7 64

[xero]

Just a bit of a question. I have trs 2006 and I was wondering whether or not it will better on a Windows 7 64 bit vs. The windows vista 32 bit os! It runs ok for me on windows vista 32 bit system. I believe it will run better for me on the windows 7 64 bit system...

My specs are AMD duo core 2gb ram @1.7GHz

Thanks
