Well I can't exactly rain down my past nostalgic experience like the 2 users the will enviably downvote or post comments not relating nor helping but I can be a judge of history.
Seeing how FM1 Front Bus Speed reaches a whopping 100 MH/z at highest clock, it won't do well and will certainly become a bottleneck real fast, so starting or running any process will slowly cap up the bandwidth on the FSB.
FM2 Allowing better architecture design for multiple processes, but still matching in contacts as of the FM1 but +1 contact, was basically FM2 just being a simple revision product. Along with FM2+ but now I am not one to bet on products from 2011. Definitely not obsolete for 3 years, I mean also inventing the technology to connect the north bridge was definitely some new push forward in processor development.
Oh an the AM3 Socket, ahh, I feel too nostalgic now, It reminds me of my first PC dream sound effects. But out of the way AM3 has about +40 contact points so better control, it is definitely common (to even meet the likes of me) but is more of what I like to call the 2012 era. I mean the FSB goes up 2x to 200 MH/z and allows a HyperTransport connection between the RAM and processor itself.
Honestly I don't know why are you buying these sockets, I would go for the LGA1100 myself but I can't help my love for Intel. But honestly speculating your using this for a Server of some sorts. Definitely go for AM3, case and point: Efficiency beats price tag, seeya.
I have seen that most of FM2 processors have integrated graphics, but AM3 don't. Does that apply to all of them? Are there more differences like that? – Oriol – 2014-01-25T04:12:28.940

FM2 processors (and some other ones as well) are APUs. AM3 is old enough that they were released before AMD started their APU initiative. See here for details. The only non-APU socket that's reasonably modern is AM3+, which sockets 32nm Bulldozer cores. See here and here for more info.

You might also consider non-AMD processors, since, yeah, they're very power inefficient compared to Intel, for instance, see here... quite detailed markup... AMD's highest end processor against Intel's previous-generation processor... there's just no comparison. The Intel CPU equals it on all-cores benchmark, with better single-threaded performance, 35% less power consumed, and it even has on-board graphics...
– allquixotic – 2014-01-25T04:23:15.907Yes, I also consider Intel, but first I wanted to know the differences between AMD sockets. And thanks for the link to cpuboss.com, it's a great site. – Oriol – 2014-01-25T04:36:35.230
