UK Gaming Computers have been a pleasure to deal with. Their service is comprehensive; they are experts in building PCs and yet they can share this information clearly. Their prices are competitive and include a 3 year warranty (which many other companies don't). Furthermore, they can meet almost any demands of a PC. I, for example, wanted a Nvidia 560 ti with 448 cores and whilst this was not available on the website, after a short e-mail exchange, this option was added to the upgrade list.
Excellent service and communication with a genuine desire to offer the best service and components possible. I would certainly recommend them and I will be returning to them for an upgrade.
