A really quick way to know your stuff would be to post total build budget and shout 'Spec me!'. People will post a spec of parts balanced in different way's depending on what you want to use the rig for. Usually a lot of people follow up with why they chose this or that part.
How good the features are depend on what you want it for. If it is for gaming and you are a bit of an audiophile, then a good sound chip is a must if you don't have a sound card. I personally cant hear the difference between most sound chips though.
If it is a 'K' series chip, you want to be looking at z87 chipsets for ease of clocking.
If you plan on going multi card, then a good PCIe set up is important.
Some boards target overclockers more than gamers, so offer a bios which can be customized for quick neat clocking and monitoring from the bios. These boards can also include PCIe switches and buttons on the motherboard to overclock via buttons and to disable cards to make multi-card set ups easier to bench and overclock separately.
Considering your budget, i would be looking to spend between 100 and 150 for a Z87 board. My top three choices would be:
G1 sniper for an awesome sound chip and half decent PCIe set up. Has UK RMA and is available in Matx form, if you cant accommodate full size boards.
MSI gaming G45 for a full size board with a good build quality considering its low price. Also sports a half decent PCIe lay out.
Gigabyte OC for overclocking and benching features. Has four full size PCIe slots, first and third run at PCIe 3.0 x16 when single card is populated and the third is x8 (on its own), when more than one slot is populated it drops down as they share bandwidth. The fourth slot is on a separate chip and is always at PCIe 2.0 x 16 i believe (its what GPU-Z) told me and a review online also mentions it.
What is the rig for?
If it is for gaming, what games do you play?
