what is the best?

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??
