I don't understand all this trouble people are having with Vista... I got Vista 32-bit with my new PC last year and I never have any problems, its much better than XP was plus its got Dx10 and games run much better.
I think people's problems are due to using pirate copies of Vista. I read most posts on these forums and others and most of the time people are saying 'I have tried it'. How can you try it without buying it ? unless its a pirate copy.
I used to use a pirate copy of XP at first but I had many problems with crashing and things going wrong. One day I bought a new hard drive and the shop was selling a OEM version of windows XP for £40. I bought it and never had the same problems again.
