Its really hard to find a good z77 board for under 100.. What are your intentions.. Are you overclocking?
If you can do 120 bucks.. you can get the msi z77 gd-45
With tax and shipping (for California) it comes out to $118.00 on Newegg
I live in Australia haha but that looks like a good option :) I was planning on getting the Asrock Z77 Extreme 4
