Overclock Your Motherboard With Your Phone
What will they think of next?
Tired of overclocking your computer, at your computer? No problem. MSI's Afterburner will allow you to overclock and check on your PC's health status when you're away.
Currently available for Android, but coming soon for iOS, Afterburner gives users all voltage and frequency adjustments as well as monitoring tools. But the true selling point is to be able to have access to all these options on a device not tethered or bound to the PC itself. Why? In case you're in the midst of a breakthrough and all of a sudden your benchmarks starts to product artifacts, instead of ALT+Tabbing out and interrupting the run, you can just fire up the mobile Afterburner app and tweak settings to prevent your system from a complete melt down.
Another scenario that might occur is that your system's overclocked heavily and crunching away at something at home while you're at work. You fire up up the mobile app and notice that temperatures are way high. Thankfully, Afterburner is IP-based so you can drop frequencies and voltages to more mild settings to avoid catastrophe.
Whatever the case may be, Afterburner is a cool concept that MSI tells us works not only with their motherboards and graphics cards, but with any other vendor's graphics cards too -- a bonus! Best of all, the mobile app is free, and the system app is free.

Why use a separate system or a phone? Why not just do it right on the machine?
Did you read the article? The software works with any vendor's products.
Secretly install afterburner on your friends computer, challenge him to a FPS Death Match, and then underclock his system right in the middle of your game.
Or better yet, get your wife addicted to World of Warcraft and then underclock the computer right in the middle of her Raid. Then use that to convince her to let you buy a new computer so it doesn't do that to her again. Instant new computer shopping spree!
