Looking at a gaming PC.

[GreyianStorm]

Ok, so the title isn't completely accurate. I'm actually looking at getting a desktop for the house (seeing as I currently only have slow laptops). I do intend to game on it as well, though I hardly expect to be playing newer games on anything above medium (considering I don't plan to invest regularly in new hardware).
This is the PC I'm looking at: http://www.currys.co.uk/gbuk/hp-pavilion-p6320uk-04144035-pdt.html
If you click the Find Out More (or Technical Details) link, it'll list all the specs.

Seeing as I'm hardly anything even near an expert at PC gaming, could you guys let me know if thats a decent/good PC for gaming?

Thanks :D
