32-bit Office vs. 64-bit Office

[Thierry]

don't kid yourself about performance. It is all marketing.

So if I see a big performance increase in a database I use daily, it's "all marketing" and I'm kidding myself ???
Nice of you to warn me... :whiste:

I think some of you guys are forgetting that x86-64 also doubles the amount of general purpose and SSE registers, so even if the program doesn't benefit from having access to more memory, it will benefit from having twice the amount of registers.

That's where most of the performance increase comes from when switching over the 64 bit, assuming you're not memory limited..
