Article Writing Method...anyone Have Any Suggestions FOR DNS?

So there is another thread in here, talking about how a person can use DNS to create articles very quickly, and it explains how to make DNS (dragon naturally speaking) work better (computer space, speed, mic etc...)...

So basically, I had tried it before, and found it was really slow, but want to give it a try again, only when I go on amazon (seems to be where people are going to get it...), I find so many options for this program, and now i am wondering which one would be best for an article writer?

So basically if you search "dragon naturally speaking 10" on amazon, I find all of these:

the "professional" version, "preferred" version, and the "standard" version?

So what is the difference between each when writing articles using DNS?

I want a version that will give me the least errors, when I speak ( I have a very clear and professional microphone), and one which record extremely fast (as I can type an article myself within 5 minutes... so It has to be faster than I am)

So does anyone have any input/advice on which one to go with, and why?


As well, does anyone know what kind of space, speed etc... is needed for this program to run optimally? I current run on windows XP, service pack 3, 2.99 GB or RAM... etc...

p.s. I am kindof leaning towards professional, just because it sounds like something I need...

Thanks...
