Hey there team
Just sitting here and wondering. If one desires to crunch with a GPU only in any type of PC - does it require one to have a x64 OS?
Say....
If one had a small Atom/Fusion board with a PCI-e port on it - and one had to choose between the older outdated Win XP or a Vista x64 install. The x64 Vista would be somewhat of a handfull for a small Atom CPU - where the XP could easily run.
Just hypothetical speaking of course...
