6.1.2 has been rock solid for me. Most of my machines are XP dual cores 1.83 or so. Speed is not a problem for me. Haven't seen it as an issue on the board, not sure if it has been a problem lately, I was past that in the early 6 series.

I truly love ERx. I was still printing paper copies until about 2-3 months ago but really felt it was redundant, so I stopped.

P2P should be fine, unless you have too many computers, but then, it has been working well for you.

I vote for 6.1.2
