32-bit vs 64-bit Vista

I know that a 32-bit Vista won't recognize more than like 3.25GB of memory, so if I were to install 4GB of memory would my system run just as good or better on a 64-bit Vista? How much more memory does a 64-bit Vista use while running than a 32-bit Vista? 32-bit vs 64-bit Vista
64-bit Vista doesn't use more memory than 32-bit Vista I don't think. However it is more secure and unlocks the full potential of your memory and 64-bit apps. I'm running Vista 64-bit and I love it.32-bit vs 64-bit Vista
64-bit vista does use more memory than the 32-bit version. Everything that is 64-bit takes up more space than a 32-bit version by nature. Don't upgrade to the 64-bit version just to use a full 4gb of ram.

Okay, thanks. But what if I was installing a second HDD and was only going to use that one for installing and playing games on, would it still be better to use 32-bit?
