Help with AMD sockets

I saw 2 processers today. A AMD64 4200 socket am2 and one that was socket 939. Is there a diffrence? Which ones better?

 

AM2 is the newer socket and supports faster memory (DDR2). If you're planning on building/buying a new system I'd recommend the AM2 (provided you have a AM2 motherboard), especially since the next batch of processors for the future socket (AM3) will also be available for AM2.

 

I'd suggest the socket 939, it's Great Proven solid CPU

The AM2 doesnt offer any real performance gains, & also too new & the MOBO's for it are too new & buggy.
For AM2 it'sd best to wait.
AM2 may prove to be short life as well as AMD has newer stuff in the works.

You didnt mention Conroe so I will it appears to be good CPU Butt over priced, it too is way too new, I expect buggy MOBO's as well.
So far it has proved to be Much more Hype, than the AMD killer it was said to be.
So I say Stick it Intel AMD socket 939 & NF4 mobo Is where the Smart Money Is & The Biggest Bang for your Buck
