Memory Available in XP Mode

I am looking to build a new PC for use as a CAD workstation with Win 7 Pro 64 bit as the OS. I will probably have 8 or 16 GB RAM. I have legacy software running on XP. Does anyone know if all of the RAM will be available in XP Mode?

I think the main problem is Microsofts limitation of about 3 GB for 32 bit OS such as XP.

I use VMWare and Virtualbox alternatives which easily allow settings to be changed (when the VM is not running).

Seems XP Mode is same, but maybe not quite so obvious how to do it.

Also, don't forget you could also build a dual-boot xp/7 machine. You won't lose performance if your CAD is intensive.

Depends how often you want to chop and change (with reboots) between the two. XP mode would be easier if often.

Thanks. The link looks useful. I'm still not sure what the max ram is but at least I know where to look to change it (once I have built the machine!).
