Cheapo H81 boards at least offers USB3.0 at the back panel, 2x 3.0 and 2x 2.0 SATA ports, PCI-E 16x 2.0 slot and unofficial K CPU overclocking.
IMO it's very hard to see how many people need anything more even for a gaming rig; 2x DIMMs today also isn't as crippling either like in the DDR/DDR2 days when affordable 8GB DDR3 sticks exist.
