A business-focused all-in-one PC, the Lenovo ThinkCentre Edge 91z’s application speed puts it on top of the all-in-ones we’ve seen so far. Thanks to Intel’s 2.8GHz Core i7-2600S processor, it cranked our UserBench Encode test to just over 95, beating the Apple iMac and delivering the highest all-in-one score to date. Throwing in the Windows 7 Professional operating system also helps. It has a Radeon HD 6650A graphics chip, which has the capability of offering accelerated computing on supported applications. It also managed to run AvP at 25fps at 1,024 x 768-pixel resolution, although that’s not exactly reason enough to break out into applause. For its $1,649 price tag, we think the 500GB hard drive, a bog-standard Seagate platter drive, is a bit stingy — even Apple can do a 1TB drive at this price. And by their design, all-in-one PCs generally have a limited lifespan. Still, the Edge 91z’s performance should help it last longer than most.
