The HP Compaq 6000 Pro joins a rather brief list of Business-centric All-in-Ones. At $1139 (as of 2/15/2011) it's not quite as cost-effective as some of the consumer-oriented or All-in-Ones on our charts. To say nothing of the Sandy Bridge equipped offerings on our Mainstream charts -- the dips as low as $850. That said, the Compaq 6000 Pro does have a few IT friendly tricks up its sleeve.

Packed behind the 21.5-inch display is a 3GHz Core 2 Duo processor -- a stalwart part, though positively ancient. Coupled with 4GB of DDR3 RAM, it earned a WorldBench 6 score of 116. From a performance stand point, this puts it right at the top of the .

The storage capacity is far less impressive -- a meager 500GB, whereas some of its consumer-oriented competition has edged closer to 1TB. If you're working in a small business environment that relies on network storage this won't be much of an issue, but keep that limitation in mind. As befitting a , the Compaq 6000 Pro runs the 64-bit version of Windows 7 Professional.

Graphics performance is surprising. The machine is packing an Nvidia GT 230 GPU -- a significant step up from the integrated Intel graphics we're generally used to seeing. It offered up 35 frames-per-second on our Unreal Tournament benchmark (1680-by-1050 resolution, highest settings), outpacing its competition by a fair margin. The , , and all failed to post playable frame rates.

Gaming is generally ruled out while testing Business machines (and most All-in-Ones), but the Compaq 6000 Pro's better-than-average performance does bode well for anyone looking to get a bit of graphics-intensive work done.
