I would like to find a motherboard that works well with my Core I5 6500. I want it to be atx since I have the room in my Ultra Case. I would like to be able to add usb 3.1 to it but it does not need to come with it.
Gigabyte GA-H170-D3HP ATX , supports USB 3.1, ATX - $88 @Newegg. Also has a USB type-c port. Note that you will get one USB 3.1 port. Even $200 motherboards have one 3.1 port. If you want to spend $100 on motherboard, get this one - Gigabyte GA-Z170-HD3P ATX, can run ram at 2400 or higher.
