Yeah don't overclock a non k cpu.. but if you already have that motherboard cpu combo then that's not the best buy.
You need a Z-series chipset if you want things like X.M.P., integrated RAID functionality, or even SLI. Overclocking isn't the only feature of the Z-series chipsets. Z-series boards can also often be found at comparable pricing to their H or B series counterparts, so I don't see any reason not to buy one, even with a locked chip.
