PC time Options

[Qrbrrbl]

So ive been thinking of replacing my PC for a while, and now I dont have a choice. My GFX card is kaput. I know the problem, a couple of capacitors have come off, so I now get the long beep - 3 short beeps when trying to start up. Long story short, it would be better value to replace the whole lot than buy a new gfx for my old PC.

Heres what I can butcher from the old:
PSU - 500W Thermaltake number, see no reason to change it.
Monitor - nothing wrong with this
Keyboard/mouse
DVD RW
HDDs
Potentially the case, depending how I feel

SO im looking for the following:
MOBO
GFX
RAM
CASE
CPU

I dont mind spending a bit more for a mobo just to try and futureproof a bit, but apart from that I just want something that will be able to play things at the top end of the games market at the moment.

Ideally i would like to pay sub-£500 (inc. case)

Any recommendations? Im thinking about £100 each for the mobo/cpu, £150 GFX, maybe another £40 RAM with a little leeway for the components and case.
