PC time Options

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.

I would second the comments about the 470's and 480's, I've got an Nvidia 470 and it's nice and all but it's crazy loud when it's pushed and I've had to spend many hours getting custom fan control software to work because of overheating issues as well mostly because Nvidia default temperature settings seem to leave the fan at low until the core reaches 90C plus and then start cooling and it doesn't like the high temps. I've manually got mine ramping up from 60C and it's much more stable now, but it's been tough getting it that way and there's still the noise level issue as it's got such a small fan on the stock model and I'm not sure I fancy ripping the cooling off a rather pricey card. The 460 I have heard much better things about with it's bigger slower fan being the main bonus.

Everything else looks pretty good and is very similar to what I'm running and that's all been fine with everything I've thrown at it so far with no overclocking at all and stock cooling on the CPU.
