Socket 754 Or 939?

I'm faced with a decision here. I'm building a PC for a friend, and he wants An Athlon 64. When I did a build for myself a couple of months ago, I used a Socket 939 3400+ for my build, and he wants something similar (3200+, 3500+) And the question is, whats the diffrence? I think their might be a slightly slower FSB on a socket 754, but other than that, I think their almost identical, I guess. Can someone distinguish the diffrence?
 
I would suggest 939. AMD will probably discontinue the 754, since it is less efficient, and if your friend ever somehow has an extra $700 or more llaying around, he can upgrade to the undogly FX series. I'm also pretty sire that 754 is single channel, while the 939 is dual-channel.
 
939 all the way. The 754 as EH said will be phased out soon - most likely by the end of this summer. All of AMD's upcoming chips will use socket 939. There's also rumors that their next gen chips will also utilize 939 for a good amount of time.
 
Yeah, I'm kinda thinking that the pair are like the Athlon and Duron processors, released in 1999-2000. The duron was the bad, Athlon is good.
 
Viper Zero
Those new fancy dancy dual core Athlons will use 939 as well.

I can't wait to get my hands on one of those babies !....

[edit:] Oh right.. Socket 939 all the way. 754 is dead...
 
Little late, but...
It's going to depend on what you want. S754 is still a perfectly viable platform. The performance difference between 754 and 939 is not MASSIVE (although it's not completely insignificant either)... the deciding factor should be upgradeability. If you want a system that you can upgrade 6 months or a year or two down the road, you NEED to be going with S939 AND with the nForce 4 chipset (which will require a PCI Express graphics card).

PERSONALLY, I went with S754. I didn't even intend to buy a single cpu A64 system (I was planning on buying a dual opteron this summer) but I found an ES A64 on ebay, which was s754, and which I had to have. So I bought it. And a board for it. And promptly killed the CPU by dumping ~4.5v into the memory controller... luckily, the guy that sold me the ES happened to have one more... which I also bought. And haven't gotten around to testing yet (too lazy to pull the sempron to put the es in). Upgradeability was a non-issue for me as the whole reason I bought the system was to run the ES. And I had no concerns about how long the system "lasted" before it became outdated. I buy a new computer every 6 months or a year anyhow, and they're usually upgraded several times between each new build, so... The A64 ES was just a toy. Just something else to add to my collection of weird, unique, and/or hard to find computer hardware.
