Gaming P.C. advice

[vshah140113]

Hi everyone, I'm looking for a gaming P.C. for my 14 year old son to use. My budget is under £800. Can anyone recommend any websites that sell decent P.C.s for under that budget as everything I've seen is over £1000.
Thanks in advance

CCL Online
AWD It
Dell (outlet and refurb)

is where I normally start, generally good consistent prices from the first two - pretty reliable benchmark for comparisons.

the occasional ridiculous bargain on the dell outlet.

Thank you @FixTheBone . I will have a look at those websites.
