Win 7 and System Upgrade

I am going to upgrade Win 7 (7100) to Win 7 Ultimate (from Vista Ultimate) in the next day or so and also want to upgrade my system (upgrade cpu, mobo and mem). My question is whether I should upgrade my system prior to Win 7 or upgrade Win 7 and then upgrade my system? Which way will Win 7 give me grief??
Thanks for your assistance

Thanks for the quick reply obsidian86.

If I do a clean install after my upgrade, will I be able to recover my current data?? I have never done this type of OS and components upgrade before. Any words of advice?? Thanks again.

Thanks for the info Dewm. Sounds like a clean install is the way to go.

You have done a CLEAN install with Win 7 ultimate upgrade (presumably based on a previous Vista licence?) and it takes 4 minutes to boot?

That would certainly be frustrating. Something seems wrong there. I've seen machines that aren't particularly special boot Win 7 64 Pro in less than a minute. Is your computer quite old? I would go into MSCONFIG and really go to town taking out startup items AND services that might not be necessary. On a new Toshiba laptop Win Vista I once had very annoying increase in boot time. It turned out that a Toshiba utility I had installed had set a face recognition service to autostart. It was trying to recognise a face for login, even when no-one had been set up for that service! Once I disabled that service the boot time improved considerably.

As to features being removed in the final Ultimate release, have you checked Paul Thurott's Win supersite? It had a fairly thorough analysis of the RC progress, and I expect it would mention if Ultimate had been pared down for release, and give details of how.
