For atx case, the asus M4A87TD EVO looks promising. I haven't used asus for awhile; I usually go by the newegg reviews. I don't recommend any nvidia chipset boards; they are outdated; the amd chipsets have more features and better value. Whatever you've heard about mixing amd and nvidia video cards/board chipsets is not valid.
I use the biostar A880G+ micro atx board, only $39.99 after rebate recently at newegg. It has 2 ram slots, runs 1600 ram, and has an hdmi port. It's a low budget board that even overclocks, but may be too small for you. They also have this chipset in atx boards without the onboard video.
I have a gigabyte nvidia chipset board virtually identical to the asus M4n68-t. It works ok, but for slightly more money, the Biostar board is superior; better amd onboard graphics and hdmi port which the old nvidia chipset doesn't even offer. If you're looking for a low priced board with built in features, and don't want to pay more for the asus boards recommended, I would get the biostar. Again, nothing wrong with asus, but your vender selection and budget are important considerations.
