Ok after another thread I made, about Windows 7 vs Windows Xp they convinced me to finally update to Windows 7. I will be getting it within the next week or two. I finally decided to do this as I saw the Demo of Just Cause 2, looks awesome, only problem is they dumped dx9. As i heard if you buy a copy of Win 7 it will include a 32bit disk and 64 bit disk. I will get Win7 Prof or Ultimate. But which version to install, 32 bit or 64 bit? Please answer in the poll and include which version you chose.
