Mynewt,

I don't play games, so I cannot tell you if there are any compatibility issues with Win7. However as an ex vista-business user, now running Win7 professional, I can tell you that ease of use has improved, and laptop speed has increased.

Perhaps you might try posting your question into google, to get more specific forum answers.

So windows 7 is worth switching to from Vista?

Would Windows 7 improve some of the crap gaming performance i get with vista?

Twee,

unless you are involved with extremely complex algorithms and very high rate 'number crunching' there is no point, as a normal user, to change to 64bit. You will not see any noticeable difference.

Vista itself is a massively bloated OS and I would suggest that you would benefit from converting to Windows 7 to speed up your PC, rather than introducing more complexity.

Is it possible to convert Vista (premium) 32bit to 64bit "on the fly" ?

What are the risks ?

Is it worth doing ?
