Ah. There are two different versions of XP, one 32-bit and one 64-bit. The problem with the 64-bit version is that you have to have driver and software support to really gain anything. Currently the only sequencer with a released x64 version is Sonar AFAIK. 32-bit apps works fine in Win64 too, but you still have to make sure 64-bit drivers are there.
The process limitation of 2GB for 32-bit apps can be lifted to 3GB using a configuration change on your system if needed. You can even lift it to 4GB if you run your 32-bit apps on Win64. With your 6GB machine this would definitely be the case and you still have 2GB free for operating system needs. Check the sticky "Memory configuration and VI..." in the Vienna Instruments forum for more information regarding this type of configuration.
If you decide to do the Win64 thing, be aware that you're in the frontline of the development and that you're wearing the guinea-pig dress...
