9 Reasons Against

Alienware Only Has Unexceptional Personal Computer Reviews

We analysed average ratings for each PC manufacturer and found that whilst Alienware has unexceptional average reviews across all PCs, Alienware has good reviews specifically for its medium processor core personal computers.

Very Slow On-Board Graphics Adapter Dynamic Frequency

The Alienware X51 has a fairly slow on-board graphics adapter dynamic frequency (only 1,100 megahertz) compared to most of the other personal computers that have been around for around the same time as the X51. Comparable spec personal computers that are a similar age to the X51 have on-board graphics adapter dynamic frequencies of between 850MHz and 860,000MHz.

Chart Edit

Quite Small Discrete Graphics Adapter Memory

Chart Edit

Only HDD Storage Medium

The storage speed of this personal computer is HDD, which is typical of many desktop computers that were released more than two years ago. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.

We compared this PC to all the other HDD desktop computers and we think the Pro 3500, the ProDesk 600 G1, and the EliteDesk 800 G1 all from HP which is cheaper is also worth considering.

If the storage speed of this Alienware PC is too slow for you then you might want to look at the DELL Precision T1700 SFF (SSD and higher rated) or the Lenovo ThinkCentre E73 SFF (SSD and cheaper).
