Question : Install XAMPP before or after upgrade to Windows 7

Hello Experts: I need some advice.

I have been running Winws XP Pro for so long I can't remember, and I have been running PHP/MySQL on IIS 5.1 for the last 6 years(Give or Take)...

I have heard many people say that Apache is the best choice under Windows 7 Professional.

So I need to know... Should I remove my current configuarion and install XAMPP on Windows XP Pro BEFORE I upgrade my OS? or should I Upgrade to Windows 7 first then Set up my PHP/MySQL and Server?

Also, which is the better web developer environment? Windows IIS7 or Apache?

Thanks folks!

Ok, if you'll replacing RAM, please check DDR2 frequency. For example, old MacBookPro 15-17"  does not startup with DDR2 800.
