I'm thinking of updating my system to an x64 one. I've previously heard that this is far more trouble than it's worth (unless you're running lots of x64 optimized software) as you would have lots of issues with drivers and x86 apps, etc.
Since then, however, I've heard that Windows 7 x64 is much more compatible with x86 than previous versions of Windows, and so I was wondering: Is there was any truth to this rumour?
Should I stick with x86 (as I play a lot of games, including older ones) or should I go for Windows 7 x64 because it doesn't matter any more? Please note, I also have 4GB of RAM.
