Windows 7 Ultimate 32 bit or 64 bit?

[acr1965]

My dell desktop has a core 2 duo processor E6550 2.33 GHz and I have 3 GB of ram installed. I don't plan on upgrading the amount of ram anytime soon. I currently have Vista Home Premium 32 bit but am upgrading to Windows 7 Ultimate. So would I notice any performance increase (or any other appreciable difference) by going with 64 bit as opposed to staying with 32?
thanks
