Would I be sacrificing much by going with this one instead?:

It leaves you, as a gamer, one PCI and one PCIe 16x slot free, has 2 fewer USB 3.0s than most more expensive boards, and 2 of the SATAs are 3Gbps. It does not support Intel's RAID, nor SRT.
Also, in general, I would only get a 2-RAM-slot board if very tight on budget. You never know when or how you might want to upgrade RAM.
A full size board might have more PCI and PCIe available, an H87 or Z87 might have more USBs, a higher-end board might have an added USB 3.0 controller for even more port, an added SATA controller for even more ports, better SLI/Crossfire support (Z87 allows flexible PCIe lane distribution), more rear IO panel ports, etc..
How much does any of that matter to you? I ended up with the ASRock B85M Pro4, because the one feature that might tempt me I could add a whole lot cheaper with a card than a high-end mobo, whenever I decide to use it (an extra USB 3.0 header). I went through all the feature differences from a number of boards, and mentally struck them all out: don't need this, don't need that, will never use that (plus, the board was cheaper then than it is now--today I'd have gotten the H87M Pro4, being so close in price). But, I'm not you, and you very well might find a feature useful now or in the future, that exists on some H87 or Z87 board, but not on a H81 or B85 one. SRT and RAID are probably the two most useful features for non-overclockers.
