Do not purchase an assembled PC if you seriously want to game. Build your own, for the same amount of money you can assemble a much faster PC.
And, that Atom processor is fairly new, Intel released them recently, they're coming out in droves to be used in cheap home PC's and netbooks.
It's definately faster than your 1.8ghz Centrino M processor, Gorman. They're manufactured using a 45nm process, in comparison to your processor's 90nm process. Much more efficient as far as heat and power usage is concerned, and a faster all around processor.
Learn before you advise.
EITHER WAY: It's very easy to assemble a PC, and plenty of people can help you. Not to mention the quite noticable savings.
And I'm not sure of minimum specs or anything, but I'd guess somewhere around a decent dual core processor and a fairly well functioning video card, to run it at 30-60 fps. ATI 4770 or 4830 and an Core 2 Duo E7400 or Athlon X2 7750 Kuma can do it. And you could build a computer with those parts at about that same 600 AUD.
P.S. I built my first PC in 2004, I was 12. It really isn't that hard.
