Decent Gaming PCS ?????

[geddes-i]

Hello
Im really wanting a new pc, one that can play games such as Half Life 2, STALKER, Flight Simulators etc in all or most their glory at resolutions of 1280x1024
I will mainly be playing fps but i would also be using it to surf the web, e-mails etc...
I have a budget of £400.00, it doesnt have to come with a good graphics card as i have a ati radeon x850xt however it is not compatible with my current computer so im keeping it untill i get a new one or i could just sell it on.
So anyone have any ideas of a good pc ??
Please reply, cheers,

the x850xt is sub-par and you will not enjoy those games with that card, some might not even play due to the newer games use shader 3.0 and anything under a Nvidia 6600gt, and a x1000 ATI does not have it.
