Father-in-law has an old Pentium D 2.80GHz 3GB RAM PC. He's running Windows XP right now, but wants to upgrade to Windows 7 Home Premium. I believe his old PC meets the system requirements, but I am concerned about how well Windows 7 will run on it. Also, I believe his older PC means he would have to install the 32-bit version? So, should he be alright with the upgrade? Mainly uses his PC for e-mail and light web browsing.
