Six $220-280 Z77 Express-Based Motherboards, Reviewed

Expanded graphics card support, enhanced on-board features that include Thunderbolt on some models, and more-robust voltage control are all good reasons to consider paying a little extra for a higher-end motherboard. Today we examine five top choices.

The divide between Intel's mainstream and high-end platforms continues to confound enthusiasts. If you go with Intel's latest and greatest architecture, you're limited to four cores and 16 lanes of PCI Express 3.0 connectivity. Those specs seem pretty meager compared to Sandy Bridge-E's six cores and 40 lanes of 8 GT/s PCI Express. But, of course, Sandy Bridge-E centers on an older core design. So, in some apps, the Ivy Bridge-based Core chips are faster. In others, Sandy Bridge-E comes out ahead. How's that for a conundrum?

Gamers simply want their favorite titles to run better. And the Ivy Bridge architecture's better per-clock performance helps make that happen (not to mention dramatically lower prices). The 22 nm process Intel uses to manufacture those chips also helps cut power consumption. And while on-die HD Graphics engine is all but useless for 3D, its Quick Sync functionality facilitates great video transcoding acceleration. Ivy Bridge-based chips seem to hit similar overclocks, but with far more conservative cooling requirements. And the architecture's biggest limitation, a scarcity of PCI Express connectivity, is hardly a problem for power users building systems with one or two graphics cards.

The PCI Express on one of the boards we're reviewing today even has a repeater function that helps overcome the tiniest of Z77 Express' weaknesses in SLI or CrossFire configurations.

This platform's battle for enthusiast market share doesn’t end with basic specifications, however. Motherboard vendors must also convince their customers that Z77 Express-equipped platforms have the features and stability to match high-end X79 Express-based offerings. We received six motherboards that attempt to prove this point (though one of the products no longer qualifies for our final analysis).

The one motherboard in today’s line-up with a 48-lane PCIe 3.0 bridge is ECS’ Golden Z77H2-AX. Unfortunately, this platform climbed $40 beyond the budget limit of today’s round-up in the time we've been reviewing it. We're tired of seeing board vendors playing pricing games based on our review schedule (this isn't the first time we're seeing a curiously-timed price move). So, since we put the work in to review ECS' submission, we're including our already-gathered data and simply withholding the board from any award candidacy.

The only other $220-280 board with PLX's 48-lane PCIe swtich is also out of contention because its manufacturer chose to focus on a different high-end feature. But what other $40 feature could be worth its cost to the end user? Here's a hint: Zeus.

Three of the motherboards in today’s line-up include Thunderbolt technology, and one even has Intel’s $40 DSL3510 dual-channel controller. Choosing between its three-way SLI-capable and dual-port Thunderbolt-equipped products must have been difficult for Gigabyte, but we’re sure storage geeks like our own Andrew Ku will applaud its decision.
