The Maximus IV Extreme can be a little bit of a scary board with all these switches, huge BIOS options and words like LN2 being thrown around. The Maximus IV Extreme is a really powerful board that if you're going to do extreme overclocking it's a fantastic choice but it's so important to know that if you're just going to use air cooling or even water cooling it's a great board. You can see with our Corsair H70 we managed to achieve our strongest overclock to date with our 2600k.
The Maximus IV Extreme also enjoys the benefits of the AI Suite software which means that overclocking via Auto Tuning can be done which is extremely easy and yields a stronger overclock than any other auto overclocking software we've tested because of the way it slowly bumps up your multiplier and BCLK separately.
At $364.99 US the Maximus IV Extreme isn't cheap; it's actually more expensive than the most expensive Z68 board, albeit only slightly more. It's a better board, though. It's got a strong feature set, great overclocking features and uses the UEFI BIOS which people like. It's also got that "ROG" feel which just makes it feel a bit more special than boards that sit under the normal naming scheme.
If you've got the money, the Maximus IV Extreme is a fantastic option for people who really want to get down and dirty in the BIOS, or simply want to make use of the auto tuning ability. Also supporting the NF200 chip, it's a great option over boards like the P8Z68-V Pro if you're looking for a big VGA setup.
Really, we shouldn't find ourselves surprised with what ASUS has done with this board, and to be honest, we're not really. It's as good as you'd expect it to be and like we just said, if you've got the money to spend, it's a fantastic option. With all boards using the latest B3 revision as well, you don't have to worry about that initial SATA issue that was present on launch P67 boards. You can easily tell if it's the latest revision as the fact it's the "B3" revision is mentioned three times on the front of the box alone.
With the ROG Z68 equivalent not out yet, plenty of stock and just some awesome performance, the P67 based Maximus IV Extreme is a great option.
