For general use, the TouchSmart 620 3D performs the way you'd expect given its components. Like every other all-in-one in its price range, the HP falls behind the more affordable Lenovo IdeaCentre B520 on every test. Still, if it's not the fastest all-in-one, or the best value, the TouchSmart 620 3D is at least capable enough to handle basic consumer applications and light-duty, consumer-oriented multimedia processing.

You can also get away with some gaming on this TouchSmart, 3D-enabled or otherwise. Estimate that you'll lose about half your frame rate when you play a game with the 3D effects turned on. Dirt 3 went from a non-3D frame rate of 34 frames per second (fps) down to a still-playable 19 fps when we turned 3D on.

This system can also handle more recent games in non-3D mode, like the demanding Battlefield 3, even at the display's native 1,920x1,080-pixel resolution. That game does not yet support stereoscopic 3D, so I can't speak objectively to its playability. I'll simply say that I wouldn't expect to dominate the leaderboards if you play Battlefield online at under 30 fps.

While the TouchSmart's performance is adequate for its specs (if not for its price), HP dropped the ball on this system's connectivity options. The lack of an HDMI input is the biggest sin, followed by the lesser evil of its omission of all other forms of video input or output. You do get a TV tuner and a pair of USB 3.0 ports, but for an all-in-one that's supposed to be the highlight of HP's desktop family, the thin selection of in ports suggests that HP is either tone-deaf to its competition or cutting costs at the expense of customer value.

The HP's power costs line up with its relative performance, which is all I really ask. It will cost you approximately $2 a month to power this system.

HP includes a two-year parts and labor warranty with the TouchSmart 620, a welcome upgrade from the industry-standard one-year default plan. You also get 24-7 toll-free phone support and a variety of support resources available on HP's Web site, as well as on the system itself. Still, the absence of any real documentation or on-system support related to the 3D display stings.

Frustratingly beset by gaffes of omission and inattention, the TouchSmart 620 3D is a dud that I cannot recommend. The biggest issue is its lack of value. You can simply get a better 3D all-in-one from Lenovo for less. But even beyond its price tag and its spec sheet, you'll find that this system's overwrought software and subpar display get in the way of its highlight features. HP can, and should, do better.
