32-Bit or 64-Bit
If you're going to run 4GB or more in that system, it'll be beneficial to run a 64 bit operating system so all the memory can be properly mapped due to the 32-bit memory limit. There are switches you can throw in a 32-bit OS to allow it to potentially access all 4GB of RAM but it is not a sure thing (dependent on other hardware). Also, iirc Windows maps your GFX memory also, so staying at 3GB isnt going to really do much for you here.
Games for Windows
There's not many games that directly require DX10 to play at the current time, but developers at some point will all take this path, and MS has already said that they will not be developing a DX10 for legacy Operating Systems as it is 'not possible' so if you're looking at these games, might as well upgrade to Vista.
Upgrade Path to Windows 7
From a UI standpoint...if what the Milestone and Alpha releases are anything like what the UI is going to be like for 7, it may be good to get some experience using a Vista-esque Operating System just to get used to the new feel.
Hearsay about Drivers/Vista64 Gaming
From what I can tell from my experiences, all the talk about Vista 64 being terrible for gaming or the driver support being sparse and slow...its just that, talk. It was true (drivers) when Vista was launched but its all been ramped up and I've yet to have any problems running Vista 64 and gaming or doing pretty much anything. They've substantially improved on the x32 emulation and it works quite well, no need to run in compatibility mode for any application (that I've run across at least as of yet).
TLDR Version
Vista x64

What do you mean by XP stuff? Open source applications will run fine under Vista as far as I can tell, I'm running OO and Firefox on my PC at home
