XP pro vs vista

[echelonphoto]

I just built a new workstation using recommendations on this site. It will be used only for photo editing using PS, raw converters, etc. I have an intel 8500 running 4g of ram, I am setup with a main drive, storage drive, and a scratch drive using a 36 g raptor. I want the ultimate speed. One of the problems I have realized is that I can only use 1.7G of ram for photoshop in vista ultimate which I have. I understand I can configure xp pro to allow 3g in photoshop. Is this true? Should I switch?
Need good recommendations.

Moved from Software For Windows to Operating Systems.

Why can't you use more than 1.7GB again?

That's the max allowed by PS under this system

Half way down the page under "Allocating memory above 2 GB with 64-bit processors".

thanks, Navid

Very informative reading. I have CS2, so I don't know if I can access this ram. Seems windows Vista 64 is the best for accessing all the ram.

If you do have a CPU that can take advantage of a 64-bit OS, you should consider the 64-bit Vista.

The only problem I have with it (Vista 64) is that there is no VPN client for it. So, I use virtual PC 2007 with the 32-bit version installed on it for VPN.
Everything else is fine for me.
You need to check to see if you can run everything you need on it.

I thought OPENVPN supports 64bit...

That may be.
But, this is what I need.

Support for 64-bit Windows Vista is not available at this time.
