Windows XP 64-bit is the new native 64-bit operating system based on Windows Server. Now personal computers can use more than 2048MB RAM while memory mapping devices to higher memory addresses.
The 64-bit version of Windows XP is almost identical to the 32-bit version. All that differs is that better memory support is now possible.
Support for GPT data disks allows the OS to act as a file server with shared volumes. GPT can partition disks larger than 2TB.
NVIDIA supports 64-bit XP better than AMD does with drivers. Overall drivers for XP are still being shipped primarily due to the huge installed base of users. We use a GTX 260 and we have 64-bit XP installed in a partition on the machine to test game compatibility and performance. We have identified some DRM problems with some old games when we attempted to install them on a newer release of Windows. This is the main motivation for maintaining 32-bit XP in a partition and resort to dual booting.
By default, 64-bit (x86-64) Windows programs are installed onto their own folders under folder location “C:\Program Files”, while 32-bit (x86-32) Windows programs are installed onto their own folders under folder location “C:\Program Files (x86)
Triple Play 2000 is the one title we have that evokes a compatibility error with the 64-bit version of XP. Today a few games have dropped supporting Windows XP. EA for example has moved to drop XP with their new Frostbite 2 game engine.

Realistically XP runs best with 20GB ore larger disk and at least 256MB of memory.
