Go to a couple of major motherboard mfg sites and compare their boards. I recommend Gigabyte and Asus as starting points. You can choose several boards at the Gigabyte site and compare them directly.
Once you have a few boards with features you like, then look for those features at a popular sales site like Newegg. Compare the prices and the quality of the makers.
Once you have a couple or 3 favorites, look them up on google and see what problems others have had with them - keeping in mind that 1000s may have perfect results for each complaint. Search this site for mentions of the model number. Download and read the manuals for each cover-to-cover!!!
And come back and ask about the specific boards then.
