My PC has a pentium class processor. The minimum system requirements for XP 11 specify a core i3, i5 or i7 processor specifically, rather than just listing a minimum speed like XP 10 did. However, it does say an AMD equivalent, which makes me think maybe it's not as choosy as it sounds. I'm running a 3.5 Ghz pentium. Should I just buy 10 or try 11?
