View and share photos from a single app, centralize all of your email accounts in one place, streamline managing messaging and social media contacts.

Works with touchscreen systems to enable tap, zoom, and swipe capabilities and it still works with the traditional keyboard and mouse so moving between windows and programs is as easy as a swipe or a click. Other cool new features include picture password, snap windows for easy multitasking, apps to simplify cloud access and storage for documents, your favorite music, and more.

AMD Radeon™ 7340
This integrated graphics card has a core speed of approximately 500MHz to 680MHz and works well for casual single-player games. Perhaps its best feature is its UVD3 video decoder which supports DirectX 11, DivX, and Xvid. It also supports MPEG 2 and MPEG4, and Blu-Ray 3D.

AllDay™ Power
Designed for those times when you can't be tied down, AMD's AllDay Power keeps your system powered up and in touch when you're on the go.

Perfect Picture HD
Clarity is so important, particularly when you need to see every detail of what you're looking at. Now, Perfect Picture HD makes that possible with enhanced resolution and contrast for digital photos, graphics, and multimedia.

Quick Stream Technology
There's nothing more annoying than watching your movies and media skip and pause while your system buffers the digital feed. Quick Stream Technology delivers smooth, and steady Internet streaming so you can enjoy the show without missing important details.

Radeon™ HD Graphics
Discrete-level performance means you get the best looking images whether you're reviewing or editing photos of your once-in-a-lifetime vacation, creating a multimedia presentation for your best friend's wedding, watching a movie, or putting together a professional-looking demo of your newly-formed band.
