Alienware X51 "Recommended Award" 9/10 Feb 2012

Recommended Award

The Alienware X51 offers the performance of a large desktop system in a far more compact chassis. Noise, temperature and power levels are all kept in check and we lose no functionality moving to the smaller case. Best of all, though, gaming on this system beats the console equivalent with ease, offering higher resolutions and more detail with completely smooth frame rates.
