eww personally i steer well clear of pc world in all of my experiences in that shop i have been dissapointed at the levels of customer service in there . The staff have absoloutly no clue at all about computers (one member of staff told me that defragmenting your hard disk was not a good idea because it deletes tiny bits of data from them ) and if you shop in there stores they also try and hard sell extended warrenties and anti virus and backup software like norton and mcafee which IMO arent the best out there for the money .And then god forbid you buy a computer from pc world and it goes wrong because dealing with the in house technical team the "tech guys " is like pulling teeth
Then if your an inexperienced buyer i also reccomend steering clear of the likes of comet and curries , understandably the staff there are just as technically inept as those from pc world and in the case of curries being owned by the same group as pc world the prices are not drastically different in most cases the same .
I usually price check at a combination of shops in the uk and then buy from the cheapest
if your looking for a prebuilt have you trtied the dell uk website because i have a dell laptop and its been a good laptop and my parents own a dell desktop which has also been no problems to us

Morgans computers -
http://www.morgancomputers.co.uk/ these sell a lot of reworked or factory reconditioned computers check the warrenty you get but you always save a great deal off the origonal price of the machine and you are still protected by the same consumer rights if anything goes wrong regardless of if its reworked or not

http://www.overclockers.co.uk/ i personally have never dealt with these as i have usually found them more expensive than all of the alternatives but i have a friend who buys everything computer related from them from them simply because he values their customer support and he dosent mind paying that little bit extra for piece of mind
