Getting a Gaming PC

[Andy]

I am going to get a gaming PC but I was woundering if any one could reconmend a good PC because I am not the best at this sort of thing (my price range is about £800 - I know it won't get the best gaming PC but it should get me an ok one).

However please don't tell me to bulid one myself as I have aksed other people on other sites and that is the main reponce I get, and I don't want to do that as I would have no idea what I am doing and known me I'd mess it up.
