I built 2 new machines this last month. I bought the least expensive ASUS boards I could find and was really happy with these cheap boards. I used a i3 H55D and a i5 P55D. Both these little machines scream and the boards were just above 100 Bucks. In my machine I have a PT6 deluxe, which was over 300. Other than SLI, I don't see the point in buying these more expensive boards. Performance of these new boards seem pretty kick ass. Quality appears the same. What are you paying more for? really?
