TechPowerUp is giving away an NVIDIA Shield Tablet, the most powerful handheld game console, which can double up as a conventional Android tablet. Powered by NVIDIA's in-house Tegra silicon, the Shield Tablet has so much processing power, that NVIDIA created its very own game and app marketplace that sells games, which take advantage of that power. And that's on top of Google Play Store, which sells games that just any Android device could play. The tablet comes with an ergonomic game controller, which gives you the kind of control you expect from a conventional game console. To participate, simply "Like" our Facebook page, if you haven't already, and fill up a short form (or have Facebook do it for you). One lucky winner will be randomly picked at the end of the giveaway.To participate, visit this page.
