what you need to know is to stick with win 7
upgrading to a new os that's not at least 3 years old is stupid
Windows 7 isn't 3 years old yet...
oh elipses, windows 7 is nothing more than an update to windows vista. same architecture.
But who in their right mind would want to install Vista on a system now? I can get the same effect as vista by removing half of my ram and downclocking my CPU from 3.4ghz to 1.4ghz.
