Value-oriented system builders celebrate new-found performance and features as Intel continues pushing its mainstream platform towards the high-end. Today, we draw a line in the sand and consider five motherboards priced between $100 and $160.

Intel’s Z68 Express chipset represents the pinnacle of mainstream performance, with Quick Sync video transcoding times unmatched by any general-purpose graphics processor at the high-end.

Unfortunately, the contradiction of a mainstream platform capable of the fastest available performance divides some motherboard designers over how this market should really be divided up. In fact, there's one popular board vendor that doesn't even have a mid-ranged Z68-based offering; everything is intended for more enthusiast-oriented environments.

Z68's issue centers on value. The benefit of Quick Sync means you either have to use Intel's anemic integrated graphics core or Lucidlogix's Virtu software. And obviously, if there's a drop of power user blood running through your veins, you'd build a Z68-based machine using integrated graphics and Virtu. Otherwise, you'd simply go the H67 Express route. One of our engineering friends even gave us a specific price of $20, off the record of course, to upgrade the chipset from P67 to Z68 and add the Virtu license. That same $20 could be put towards a couple of extra controllers (USB 3.0 or SATA 6Gb/s) and a beefier voltage regulator on a P67-based model, undercutting a manufacturer’s ability to present Z68 as a more attractive implementation

On the other hand, Z68 Express sports a second unique feature that targets buyers who can’t justify the expense of a large solid-state drive. SSD caching allows small flash-based devices to act as nonvolatile cache for a larger hard disk, giving buyers on a budget a performance tease, as reads get accelerated over time, while writes aren't helped much at all.

What this means for Tom’s Hardware is that a market accustomed to sub-$140 P67-based motherboards must be asked to consider spending up to $20 more in order to retain the same on-board components, upgrade to the Z68 chipset, and gain access to a Virtu license. With that set as our target limit, all but one of the boards submitted for today’s comparison was completely qualified.

With production only beginning to ramp up, MSI had to do a little finagling with rebates in order to qualify its Z68A-GD55 for a $160 roundup. Currently listed at the same $170 upfront cost as the discounted Z68A-GD65, both motherboards are now available with an additional $20 rebate. The full price for the higher-model board is $190, so we expect to see a $20 price delta between these two models after Newegg's temporary discount expires.
