Tempted by HP's svelte Omen gaming laptop, but need even more horsepower? Say hello to the Omen Pro. It shares the same aluminum 0.78-inch, 4.68-pound frame as its gaming sibling, but it packs in faster Core i7 processors and an NVIDIA Quadro K1100M graphics card. It also shares the original Omen's unibody aluminum case and 15.6-inch 1080p touchscreen, and it sits right alongside HP's ZBook workstations, except it balances style and hardware prowess. The Omen Pro is available today, but at $2,199, it's clearly targeted at the graphics-hungry professionals actually making games, and not just people looking for their latest Far Cry fix.
When it comes to storage, you've got a choice between HP's 256GB or 512GB Z Turbo PCIe solid-state drives. Its RAM capacity tops out at 16GB, so if you need even more memory, you'd have to forgo style for one of HP's ZBooks. And of course, the Omen Pro runs Windows 7 Professional -- because anyone buying a machine like this wouldn't stand for Windows 8 anyway.
