Hello, Recently I've bought a new Packard Bell Laptop. when installing, it (sadly) only contained a x86 version of Windows Vista. Now I've upgraded to Windows 7 x86 Professional. The laptop does have a 64 bits processor and 4Gb ram, so I reckon an x64 OS would be recommendable. I would like to install Windows 7 x64, but, of course, I'm going to have to do a fresh install. This might involve many problems, like finding the right drivers, installing everything anew etc. So I was wondering, since I've never used a x64 bits OS, do you really notice a significant difference? I know you are going to need x64 software, such as the x64 flavour of iTunes, Office etc. What would you recommend, fresh install with x64 or lack it? Cheers.
