The Socket AM3 Connector is compatible with the AM3 and AM3+ processors, but not AM2 or AM2+ processors, which have 940 pins instead of the 941 pins of the AM3/AM3+.
You can use an amd sempron or an amd athlon II with an am3 socket, but when am3 was released it was meant to be used with the amd phenom line of CPUs. You can use all three: amd sempron, amd athlon II & amd phenom.
If you have an AMD Duron processor, those run on a Socket A motherboard, which is very outdated in 2011. No major retailers sell processors for such an old socket. I would recommend an upgrade, as Newegg.com has Socket AM3 (the newest AMD processor socket) Sempron processors for as low as $36.99 and AM3 motherboards for as low as $39.99.

It depends on the type of AMD processor. The current AM3 generation has 938 pins.
Well, all motherboards are socket motherboards (When we're talking about the personal computer, of course!). The socket and socket type are what determine which processor you can use with your board! Take AM2 / AM3+ for example. Motherboards with the AM2 / AM3+ socket can house processors from the Phenom and FX-X family of AMD processors. It is very important that you make sure the socket type on your motherboard and processor match if you are considering doing an upgrade-- Different socket types aren't compatible!

No, you can't. Gigabyte-GA990FXA-UD3 uses AM3 socket and supports AMD processors only. While 2600K is Intel processor and it uses socket LGA1155.
No, it will not. Asus Sabertooth 990FX uses AM3+ socket which accommodates AMD processors only.
No, it will not. Asus Sabertooth 990FX uses AM3+ socket which accommodates AMD processors only.
No, it will definitely not fit. If you have an AM3+ CPU like for example an FX-8150 or an FX-6100, a Phenom X4 or even an AMD Athlon II X2, you have to use an AM3+ socket, or in the case of the Athlon II X2, or X3, or X4, or the Phenom family of CPU's you can use AM3+'s predecessor: the AM3, as well as the AM3+. However, the 939 is a much older socket which is not compatible with most modern day AMD CPU's.

You'll have a great fast computer. The Gigabyte GA-970A-D3 has an am3+ cpu socket which is meant to be used with ADS's FX series processors. The AMD FX-8350 is an eight core cpu that clocks at 4.0GHz, it is one of AMD's best processors available as of 2013.
