I'm looking to upgrade from Vista to Windows 7. I currently am running a 32 bit processor but my computer says it is 64 bit capable. So, I apparently can upgrade to the 64 bit, but firstly is worth upgrading, and secondly, will it cause any unforeseen issues with my computer with drivers or anything like that? And can I do a straight upgrade to the 64 bit, or do I essentially need to start from scratch? any thoughts would be appreciated.
