I remember back in Windows Vista days (and early Windows 7 builds) doing extensive 32-bit Vs 64-bit testing and the 32 bit system outperformed the 64-bit in everything from startup time to application launch time. This being said, PAE doesn't seem to work great and out of a lab, when you start running multiple applications, you will usually want 4GB memory on the smallest system and typically 8GB, so, I think 64-bit is worth the sacrifice! (No idea if still true, haven't done tests like this in many years)
