# of DIMM (RAM) slots
# of USB 3.0 ports
# of SATA ports
PCIe2.0 vs 3.0
So count up your connections of the rest of your build and see. But the B85 is better than the H81 in every respect.
The combination of either with a i5-[xxxx]k processor isn't optimal though since the k is a more expensive (generally) version of a non-k chip with the express purpose of overclocking. And neither the H81 or the B85 is built with overclocking in mind.
