Bro - check out http://www.newegg.com
I've built my rig entirely from components I've bought from them, and not only do they have killer prices but their delivery rocks. What's especially cool is that customers can file a review of whatever product they purchase on the website, and so you can get a super clear view from other people who've bought the same thing what its positives and negatives are. I suspect that you can find some killer info on their site about whatever mobos you are interested in. All I can say, again, is that I built my entire rig from stuff I bought from them, and saved major cash. I ordered on a Tues night, by Thurs morning, I had the merch in hand. I am not connected with them in any way apart from being a customer, but dude, Newegg rocks. -- J.W.
