Whew, this is an in depth question. Here's a crash course.

Different processors have different socket types they are compatible with. The main ones out now are socket 775 for intel and socket 939 for AMD. These numbers only stand for the number of pins on the processor.

Numbers are not a fair way of judging the 'goodness' of a socket. They do provide a general trend, though. The trend is more is better... sortof. Inside brands this is kinda the case.

You pick your motherboard AFTER you choose your processor. There are infinate differences between advancements between sockets, but I'll let someone more versed take care of that.

Socket 478 and 775(LGA) are Intels, and socket 754 and 939 are AMDs.

Socket 478 is for real old systems. It is worth it to go 775 Instead. Intel that is.

socket 754 is for AMD chips while kinda old it still serves it purpose on lower end machines but does not support Dual Channal.

939 is the at the moment and in my opinion the best socket out there. Its AMD and can accept 64 Bit prossesors.

As for motherboard brand names, some are better then others just ask and we will tell.

just a quick and kind of pointless side not...the LGA775s aren't in reference to pins in the same sense the other ones are....LGA is a 'Land Grid Array' meaning the pins are in the motherboard, and the CPU has little 'spots' on it that the pins in the motherboard make contact with...really weird, but yeah..was just a little side fact.

when AMD's first came out they had socket 754, socket 939, and 940, no one knew what to choose from at first...but socket 754 didn't have dual channel capabilities, and beyond that they held some of the lower processors, like it was mainly for 2800+, 3000+'s like that...socket 939 was meant basically for the desktop environment, included dual channel RAM capabilities, and housed the higher up CPUs, like 3800+, 4000+, etc..etc..

Socket 940 was primarily for servers and the FX chip was originally on this one, but then later became available for the Socket 939 series....socket 940 is meant for opterons (IE Server CPUs) and requires registered RAM with ECC

It was in this last couple of years where different sockets were really confusing, but for the most part like fghtin said, the trend has been the bigger number, the more pins, the better the socket and it's capabilities
