Well I have various costumer with both versions side-by-side.
Nowadays, unless because of a legacy application, particular scenario or anything unusual, I’m deploying x64 almost all the way out.
These days, I have people that can’t work anymore with less than 4GB of RAM, so 64 bits is needed. Even those that can do their work on 32 bits are prepared for the future. I think this way I can improve the ROI.
