As you know, Office 2010 client now comes in both 32 bit and 64 bit versions. The question is, should you go with 32 bit or 64 bit?

64 is bigger than 32 .. so 64 is better no? NO!

Given a choice, or unless you have a very strong reason not to – GO WITH 32 bit.

Why is that? Here is why -

32 bit apps actually work better on 64 bit OS’s in most scenarios due to WoW, and the additional 64 bit VLSW calculations.
If you have 2007 installations to support, SharePoint designer 2010 cannot be used to work with SharePoint 2007 sites. So you will have to install SharePoint designer 2007 32bit side by side with SharePoint designer 2010 32 bit side by side. So you cannot mix and match 32 bit and 64 bit here. Of course you can virtualize and not have this problem to begin with :-D.
64 bit office will break many things on your SharePoint experience for that client – example, that fancy datasheet view won’t work on lists. 32 bit office apps don’t have this issue.

There are some extreme situations where you DO want 64 bit client apps though. Specifically if you have HUGE excel sheets to work with, then 64 bit office client excel is much better than the equivalent 32 bit excel.
