This was a really interesting review. I've had countless Asus motherboards over the years and I really love their products but it's clear this is a total disaster. £330 is a lot to ask for an LGA1155 Haswell motherboard in my opinion even with Quad-SLI support and PCIe switches.
As you can see in my signature I have the Rampage IV Extreme and it came with that OC Key thing which is completely useless to me.
Just to go on a bit of a teeny-tiny rant, The Rampage IV Extreme (X79 board) cost about £340 retail I think. And it came with this OC Key which has a DVI pass-through to show you your overclocks, fan speeds and temperatures on your PC screen as an on-screen display. The key is so long that if you use it your PC case has to be like 9 inches away from the wall and it doesn't support Dual-Link DVI.
Now who in their right mind is going to spend £340 + £220-£440 on a Mobo + CPU on X79 and not be using a 27" 2560x1440 or 30" 2560x1600 display? The reason I say this is because those displays use DVI-Dual Link, it has twice as many metal contacts on the DVI connector as normal DVI and thus makes those screens completely incompatible with the OC Key.
So not only do you need to move your case 9 inches forward, you need to be using a 24" or smaller display and they make you pay for that key thing regardless if you can use it or not.
It is gimmicks like that which mar their otherwise good reputation and I was pretty disappointed to see them bundling yet more useless shit like that with this Maximus VI Extreme. Not only does it cost you money to get something none of us would use but it is poorly designed with the cover easily coming off and the SATA cable at the bottom.
This board and the general direction Asus has been going in for the past year seems at odds with who they should be. Gimmicky rubbish, overpriced underperforming boards. And I agree with tom that they are seriously misjudging the market by aiming these Republic of Gamer boards at hardcore overclockers, that makes no sense to me because people who are going for record attempts don't want all this extra fluff. Gigabytes OC boards get what hardcore overclockers want they keep it as sparse as possible as not to burden the processor with extra faff, sticking things like sub zero temperature sensors on these RoG boards makes no sense to me whatsoever.
If I was advising Asus right now I'd say get rid of these Overclocking accessories, they are a waste of time and make a new brand for hardcore overclockers, sticking RoG in with that crowd is doing a disservices to both camps.
