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.

So which AMD chip would offer similar performance? Any money savings to be made there? And is the 470 a significant upgrade over the card there?

On second thought's I retract that about the Thuban, I was basing that more on multi-threaded operations, which is more business processing. If you're setting up a gaming platform primarily then the i5 will be better and they're both around the same price.

As for the 470, there are some 460's that have been obscenely overclocked to be comparable to the 470, such as the Palit one, but these are also obsenely expensive. The performance on a stock 470 over the Gigabyte 460 should be around 20%, based on the benchmarks on the link I posted further up this thread
