I think you want to know why there are so many different types of motherboards...and the advantages/disadvantages of one type compared to another. At least, that's how I interpret your query.
, for basic, understandable fundamentals. And http://computer.howstuffworks.com/motherboard.htm
FWIW: The How Stuff Works site is a good site for the kinds of questions that many of us either ask or would like to ask.
Different motherboards ARE "better" than others, not necessarily because a magazine or website or manufacturer says so...but because of user options desired, increased features on one board vs another, and improved technological implementation from year-to-year.
Contrary to what some persons say...I don't believe there is such a thing as a "bad" motherboard (unless it's DOA and I've not had one of those). I believe that users tend to develop preferences for boards in the same manner that some develop preferences for the "latest, greatest" processor of the year. That doesn't mean that last year's processors suddenly become "trash", fit only for the garbage pile. It just means that certain users like to spend their money more often than some of us who buy a system and run it until one of the components dies
Back to "better" boards...IMO, any board manufactured this year...will probably be "better" than a board manufactured last year...for certain users. Enthusisasts and gamers are the persons whom all those expensive, shiny, new boards are aimed at...because they are the only ones who are truly interested in imperceptable speed differences in System A versus System B.
Most of us users...are just happy to have a working system that does what we want it do when we want it done...not enthusisasts, not gamers (I'm not a gamer or enthusiast)
I frequent another forum where the regulars used to routinely preen themselves on how "fast" their systems were. Not that they could really detecct the differences...they had to use benchmarks (posted) as the standard, with the system with the highest benchmarks being possessed by the "stud of the day"
That sort of thing has tailed off in that particular forum, but it's that mentality that possesses certain persons. For those persons, a motherboard made last year is probably "unacceptable", while that same motherboard would certainly be an upgrade for a clown like me
. I just barely got a dual-core board installed and I see that the big push now id quad-core for consumers who don't understand or appreciate what quad-core might be.
Anyway...the best advice I can give you is:
a. Get the basics down first.
b. Do some comparative window-shopping. Go to site like www.pricewatch and just browse through the more expensive boards advertised there. Then go online and read a couple of reviews about said boards. Then see if you can go back about a year and read a few reviews of the "then" hotshot boards...see how much they are today and evaluate the differences between then and now...in terms of cost and in terms of features.
My last comment will deal with features. There is no point in focusing on motherboard features that a user is not going to utilize. If a review says this board is great for Crossfire or SLI, but you know that you have no interest at all in such...that's not a useful feature for you, but it might be John Jones.
Others will provide their (not-so-lengthy) comments

Just pick 2 or 3 to read and you will probably come away with a good understanding of how complex your answers could be.
