Performance hit moving to 64-bit?

I'm thinking of moving from Vista 32-bit to Windows 7 64-bit in order to upgrade my RAM from 2Gb to 6Gb. This is mainly for Empire Total War's benefit. Is there any performance penalty running 32-bit games (as I assume ETW is, and certainly the majority of my other games are) on a 64-bit OS? I was all set to order the necessary pieces but then found out that 32-bit applications are emulated in W7 64-bit, which puts me off somewhat (to me 'emulated' means those horrible console emulators from the early 2000s which would crawl like a dog on a computer with 5x the processing power of the console :p )

Can anyone running 32-bit games on Windows 7 64-bit tell me whether there is a noticeable performance penalty? From Steam's hardware survey I assume there must be quite a few of you out there!

PS: Not sure whether this should be in the gaming forum or the Windows 7 forum

you shouldn't see any performance hit. i run empire total war on win 7 x64 without any issues

My concern was that running Empire on my system is close to begin with (Q6600, 8800GT) so any performance penalty on x64 would probably cause big enough problems for the RAM upgrade not to be worth doing.

Vista is slower than win7, if anything you will see an increase in performance.

there is no perfomance hit in 64 bit at all....
the only gain you will get is that 64 bit programs uses less ram.
For ex: if you load a photoshop 32 bit it uses around 70MB...and photoshop 64 bit uses 46 MB ram.
If games are 64 bit..they ll be using less ram..on 64 bit OS.
Win 7 works the fastest for me..better thn an 64 bit xp...for gaming win 7 64 is the fastest even for HDD operations like copying reading etc stuff cze it has a better improved ntfs for logical space.
So you ll be having smoother games, better performance overall.

O/S has slightly higher memory footprint, but this is offset with larger memory support.

You should be fine. I've used both 32bit and 64bit Windows 7 , and there is no visible difference in performance. The extra RAM capacity should be a benefit.
