Need Help With £400 Build

[jordie240991]

My brother recently sent his computer in for a repair at pc world and it turns out that it is un repairable so they have refunded him with the sum of £380

I am a novice to building computers and would like some help with building him a good "Gaming" build that will perform well on games such as crysis 2, cod4, bad company 2 at med to high settings.

His old build was on the lines as follows:

AMD 945 black edition processor @3.4ghz
4gb ram
gigabye 5750 1gb
750gb HDD

if you could give ideas and links to parts that are sorced from high quality sites such as scan and aria i would be very greatful indeed as he is currently using a 15 year old pc that can barely run minecraft =/
