Here is the context of my question, but feel free to discuss any of the Z87 motherboards, etc.
It is finally time to upgrade my system. The old Q6600 was good to me, but I'd like to take advantage of the power savings of the new hardware and I need USB 3.0 for data transfer to HDD and flash drives, etc. I have an HD 7950 and a Samsung 840 Pro 256, bought recently in anticipation of this upgrade, that will be reused for this build. I have decided to spring for the i7-4770K but I'd like ya'll to discuss your opinions on motherboard choices. I know that they are all just announced so this is just a feature oriented discussion with very little real experience with the chipset, individual motherboards, etc. I am not worried about the USB bug in the chipset, I very rarely have a USB key left in the system anyhow. I was thinking of sticking with ATX form factor and I was planning on using a Silverstone FT02B as my case, but I am open to anything really. I think I would like to avoid any motherboards with active chipset cooling. The FT02b has plenty of airflow to keep the components cool anyhow.
So what do you think about the Z87 motherboards that have been announced? Any favorites? I am currently thinking about the Asus Z87 Expert and the Maximus VI Hero. But I am open to any/all suggestions. What do you like? Should I be sure to get a mobo with thunderbolt support? What are the important features for this generation of motherboards?
