I'm running Win7 Ultimate x64 and I just downloaded Office 2010 and Visio 2010, since I'm able to run both x86 and x64 I decided to get both (I have an MSDN Subscription). However I know there's more support for x86 when it comes to Office products, but I'm curious if it'd be worth while to install x64?

I could always go x64 with the next version of Office when the support for it is better, what do you guys think?
