|Thanks all for your reply. Argh I didn't realize only certain motherboards would support Windows x64 not all modern motherboards as I thought. My hardware is not suitable for x64 then.|
Right. For average Windows XP users, 2-3GB RAM is plenty. There are no reasons to have anymore.
As for me, I'm running SAP. SAP is a monster when it comes to RAM and disk space. That's the only reason I'm thinking of make use Windows x64 so I could have more RAM.
Also, seems like a mess with mixing x86 & x64 applications if I took Windows x64 path.
