When I replace my XP games machine it will be an I7 with win 7. no win8, too much stuff I'll never use.

I think it's also time to replace my laptop with one I can record HD gameplay videos on WinUAE (so that will have to be an i7 with proper GPU on the motherboard) but Win 7 is such an ugly interface it is pretty certain I will replace it with the Vista GUI which at least looks smart. It is mostly for security though more than anything else, XP just gets slaughtered at the slightest hint of a TCP/IP connection these days hmmmm
I have had to experience the stupid Win 8 interface once this year and I can promise you it is not something I would ever install. If I have to stare at the screen and wonder WTF it is trying to tell me via this interface when I have an IQ of 137 then clearly it is Microsoft who is deficient not myself
I had so many family members ask me how to do something on Skype for Win 8 I had to just tell them I don't have a Win 8 machine and if they install and older version there problems would be solved! haha
If however you use some obscure emulators you can not use anything past Vista due to screen access functions provided to applications that have been removed in Windows 7.
XP is the oldest I would go though, if it doesn't run on XP then forget it IMO (DOS games were better on Amiga most of the time and Windows 95/98 is next to impossible to get running without problems on modern hardware).
