there is no best. just different revisions. read up on what each revsion adds to get an idea of what they mean.

some mean different fabrication size:

e.g : 130nm to 90nm

some mean the instruction prosses' that it can handle and understand.

e.g SSE1, SSE2, 3Dnow!,

the amount of power they require and the clock speed.

tada

heres a list of 939s

also. you sure your 3200+ is a sandy core???
are you lying?

cpuz. will tell you everything you wanted to know or could know about ur CPU.

i didn't know that AMD made a sandy core of the 3200+. i thought the sandy core was high end only... screen grab??
