I found this article on the internet

Difference Between Socket 754, 939, 940

Any truth to this in you people's opinion?

Wow. He said the 939 shows no benefit over the 754. That is just wrong. I guess the main benefit is that AMD is actually using the 939 and not the 754.

Well, I think his point (which he made badly) is that while synthetic tests will show the higher memory bandwidth of the 939 chips, that doesn't always translate into a performance advantage in real apps/games. If you're not bandwidth-bound, then the move from single to dual-channel won't get you much.

According to AMD at their tech tour meetings, dual core support will be doubtful for most 754 boards.

The only possibility of dual core on a socket 754 board is if it has a Socket 939 on it too. Since AMD has only produced dual core Athlon 64s on the Socket 939 Platform, and they will not be moving to their new one.

Heard a rumor that AMD is planning on phasing out the 939 in the near future. Supposedly the new socket will be called the M-2 or something to that nature. I bought a 939 cause it was supposed to be the socket that would stick around like the socket A did for so long. The M-2 is supposed to be comparable to the Intel LGA 775, the pins on the mobo instead of the proc. Hopefully just a rumor though. Was in an article in Maximum PC magazine.

It's no rumor, unfortunately. AMD just launched their FX-60 chip, which is the last Socket 939 release before the introduction of M-2. I'm not exactly sure why AMD is making the transition to a new socket so quickly, because I've read that there would be no real speed or performance benefit from going 939 -> M2. Pretty much the only thing M2 is said to add is support for DDR2, which is funny considering how AMD was so against this standard when it was first introduced.

AMD wants to keep up with the times and not fall behind. DDR2 is reasonably priced now, AMD just was really against it because their CPU's memory controller was designed for support for DDR only. That is most likely the reason for the transition, so people won't try to stick those chips into boards that use DDR2.

I dont care as long as they can get the latencys down on ddr2. That and I dont know why they would want to put the pins on the mobo instead of the processor, seems like a way to cause more problems resulting in more mobo sales due to igmo's getting rowdy with installation.

I'd rather buy a new mobo than a new $300 cpu though in most cases... Just me though..
