Well, as long as you get a mid-ranged board for Z87, you won't be held back at all in terms of overclocking (unless you get the super high end Maximum VI Extreme, which has BIOS problems that DO limit its overclockability).
On 990FX, you pretty much have to get a solid motherboard to get the best OCing possible. In terms of AMD overclocking, the quality of VRMs and other components used on the motherboard are paramount to the best possible overclock. Especially if you want to start hitting clock-speeds of 4.8+. And even then, you are going to need a solid chip to get past that barrier.
In terms of Haswell, you can do all of that on a good solid mid-ranged cooler/board. Its not exactly the same with AMD as there are temp limits that you don't want to go over (64C I believe, might be 62.).
And if you went the Sandy Bridge/Ivy Bridge route, its even easier to get 1Ghz over stock on a mid-ranged cooler/motherboard. And if you invest in a better cooler, ~1,3 over stock is very easy to do on IB/SB.
