silly question - the great majority of us on this forum have chosen 7 - the clue is in the domain name.
i'm also surprised 7 isn't performing well on your hardware - driver issues?
a lot of us have spent many years with xp, and it's always difficult stepping outside of your comfort zone, having to learn how to solve new problems and using new methods and techniques.
but that's what i like doing, learning new stuff - it's one of the things that separates us from the animals (and indeed, the duller majority of humanity).
back in the day, my sinclair spectrum fulfilled all my computing needs, but time and tide move on, and it's up to us to move with them, unless you like being left behind tinkering with antiquated technology.
