I have been looking into these motherboards and I am very interested in basing my 800$ build around them. This will be my first build so I am a bit confused at telling the difference between all the asus z87 models. I think the asus z87-a is the basic model, and I think the z87 deluxe has more features. Is there some models in between that perform better than the z87-a, but are less expensive than the z87 deluxe
