Not as compact as other VR-ready competitors
The Dell XPS 8900 SE is the antithesis of an Alienware when it comes to looks, but that doesn't mean this PC isn't sexy in its own right. While Dell's Alienware-branded PCs are known for their glowing lights and sci-fi–inspired architecture, the XPS is an unassuming black box with a glossy front panel and an elegant upward curve along the top.

The PC's front panel sports a sleek, silver border, with a honeycomb-like vent near the bottom. While the XPS lacks the fully transparent side-panel that's practically a standard for modern gaming desktops, there is a small grille on the left side that exposes the green glow of the machine's Nvidia GTX 970 graphics card.
Ports and Upgradability
In the back, you'll find four USB 3.0 ports, two USB 2.0 ports, and a full suite of surround-sound audio inputs. For your video needs, there are three DisplayPorts , one HDMI port and a DVI connection on back of the PC's GTX 970 graphics card.
Accessing the XPS' components is a cinch.
Accessing the XPS' components is a cinch. After removing a single hand screw from the back, you can easily slide off the PC's side panel and gain access to the machine's GPU, fans and storage. You'll need a screwdriver to swap out any of those parts, however.

I jumped, climbed and swam my way through Rise of the Tomb Raider's gorgeous cliffs and rivers at a smooth 60 frames per second, even with the graphics set to high at 204x 153The system even handled a bit of Tomb Raider at 4K, though I experienced occasional frame-rate drops to below 30 fps.

On the game's benchmark, the XPS churned out a silky 54.fps at 1080p with graphics cranked to the max. The PC maintained a highly playable 39.1fps at 204x 1536, but sank to a chuggy 13.6fps at 4K.
The XPS ran the notoriously intensive Metro: Last Light benchmark at an impressive 66.fps at 4K on low settings. However, the game slowed to an unplayable 13.6fps with graphics maxed out.
The XPS scored a 2,51on the 3DMark Fire Strike Ultra test (which measures 4K performance), beating the GTX 970-powered Asus G20CB (2,153) while topping the Alienware X5(2,446) and trailing our 3,72gaming-desktop average..
