Best Computer for Photoshop CS5

I'm shopping too and I'd use a CPU with a lot single thread power.  Intel i5-750 for example has the Turbo mode, when PS only uses one core of the CPU.  If I understand correctly multiple CPU's and graphics cards are not very helpful for PS.  A Radeon HD5750 should be fine.  Other cards are maybe cheaper or a bit faster for that price, but they're hotter and less efficient too - I like passive cooling. 

And specifically? What's the budget? Do you want to run PS extended or PS Standard? Do you want to run otehr apps? Pretty much any computer you can buy these days should be able to handle PS, even the 300 Euro ones. Which one to get really comes down to more specific details...
