> Yes, Win7 comes with DVD's for both versions(retail copies do at least).
Only the retail version comes with 2 DVDs, afaik. I bought one of my Windows 7 keys through my daughter's school and it only came in the flavor you chose. You can use the same key to install either 32-bit or 64-bit version though. You can always download the ISO file and put it on DVD or flash drive.
