Advice on £500 rig.

[Razor-BladE]

Just need to know whether this is an ok spec for the family pc. Helping a mate's brother build theirs.

They won't be upgrading or extremely rarely.

I'm gonna get a cheap m/k for about £20, but a little bit over £500 for it all won't matter.

This comes up to £470 so i guess a tinyy upgrade could do. Or is that ok as it is?

I wasn't sure between the Q8200 (£104) or this??

Or the OCZ 600w PSU or the Corsair 450w modular?? I'm not sure the Corsair would cut it though.

The graphics is an overkill for the rig right? Better going with a 4850/4870 512mb and upgrade the other parts?

EDIT:
This is just about pushing it at £500... but what about this?

Or would the Q8200 be better?

Yeah they'll be gaming, well one of them will be. And it'll be for more than 2-3 years use.
I was considering AMD but i'm more familiar with Intel so i just put that in initially.

EDIT: So something like this perhaps?
