Do i need an expensive lapto?...And can you recommend a good one?

Right I want a laptop.A gaming one.The internet isn't a big priority for me, especially since it usually adds a bit more on what you need to spend on a laptop.Anyway I can afford £940 if I get a laptop from currys.£840 from anywhere else.I'm in the U.K by the way.I'll by a laptop of renowned sites like Dell.IF(and it's a big if)you found a laptop so amazing I HAD to have it I could wait longer and spend £1602(approximately)at currys or £1502(approximately) elswhere.Please do help, as I have No idea whatsoever on what price I should be paying.

Thanks in advance...greg.

Can someone tell me if this is any good or not?
