Generic question

Actually I'm lost in the sea of motherboards, and knowing nothing, i ask... what does make a motherboard cost 180$ and another 350$? What's the difference? Thanks!

also chipset, bundle, power regulation, I'm sure there are more.

I missed to say intel x58. Looking at the comparison charts of the offical websites, they seem all the same. For example the big difference between gigabyte UD3 and UD5???

The above posts give you a fairly good idea. I guess you could say it's a similar thing to buying a car. The more you pay, generally, the more features you get in terms of, features comfort, performance, safety, technology and even build quality.

I've always advised that your components should, for the most part match up. Don't buy the latest and greatest processor if you end up sticking it in a poorly manufacturered, low end motherboard. Try to weigh up what you need and match the parts accordingly to your requirements
