Hey gurus! Been lurking for a bit dead:, I know), but I come back with a question I would appreciate some help with. Currently running Vista Ultimate 64-bit OEM, and I'm looking to change over the Windows 7 Professional 64-bit, OEM if possible. Problem is, from what I know of OEM Windows, they tend to cast voodoo magic on one's motherboard, to link it to that installation of Windows, or something to that degree (clarification, please?). Will that cause for a bumpy ride in terms of moving from Vista to 7 (OEM to OEM)? I'm looking to reformat my current HDD, install 7 afresh if possible. (And grab a Q9550 and maybe an HD58_0 while I'm at it. :roll Thanks in advance, guys.
