Thanks for the info Joss I appreciate your input. This rig will be purely for gaming only as my adult son has autism and plays a lot of online tournament games mostly BlazBlue: Cross Tag Battle but also other games mainly at 1080p. Gaming has helped his social skills and he has met some very nice gamers from all over Europe who know of his condition and about 15 of them including my son met up recently for a big tournament game in London. My son came 15th out of the 100 who played BlazBlue he was well chuffed.
The other company I was looking at was Chillblast (they are within a 90 min drive) but I will look at overclockers. My biggest fear ordering online is trusting a courier company that the pc builders will use. They build expensive rigs for people and use the cheapest couriers to get it to customers and there are some horror stories about the state the pc arrives in.
Thanks again Joss.
