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 £90 and £130.
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 centres on value. The benefit of Quick Sync means you either have to use Intel's anaemic 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 [Ed note: this translates to roughly £12.50 but here in the UK, we don't have any friends to offer us money], off the record of course, to upgrade the chipset from P67 to Z68 and add the Virtu license. That money 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-£100 P67-based motherboards must be asked to consider spending about a tenner 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.
Editor's note: According to our brothers across the pond, MSI had to do some price finagling to ensure its board met the $160 price limit required to make this round-up. You should also know we couldn't find this board on any of our favourite UK shopping sites (even Amazon came up empty), though that could change any time.

New technology that promises efficiency gains but ends being used only for fancy graphical effects. Isn't that a brief summary of the modern software industry?
Anyhow curious to know hoe could this board with such high temp diff can consume so less energy, as ultimately heat is also energy and higher difference means higher wastage. Any clues??
