I like 6.0.9 There are speed issues on P4s but I am mostly using dual cores I picked up cheaply. Some of my machines are P4s and it is tolerable on them too.
Speed issues are only with Rxs and presumptive diagnosis lookup. Otherwise works well.
Prescriptions, while slow are better. Of course you can do the 5.1 things like put in grams and things. It is easier to work with allergies as well. Rx box closes automaticaly after you eprescribe, don't have to do it manually.
The MU stuff is highlighted so you can see what you need to do. You can check a scorecard any time you want.
