yup yup - and some boards allow more OC, have higher native memory clock support, offer for technical support (warranty xP), nice colors and heatsink designs lol.
Which is something i always aim for. I'm picky when it comes to motherboards - i have "minimum requirements" that a board has to meet or its out of the picture. I do alot of OC'ing, Gaming, and every now and then benchmarking. x)
But if you don't do much of anything like that - well then you probably don't need an expensive board. Much like a car. You just need something that gets you from point A to point B - but you have those people who like to have an Audi, or a Mercedes. Maybe a Ferrari? xD
