4GB RAM, 2.4Ghz Quadcore, GTX450, 450W PSU and a fast HDD is what I would recommend for this game. I just stated the cards required for max settings as a compairson. But a GT530 is definately waaaaaay behind anything else and will give in when you try this game on it. It's a special ultra lowend OEM GPU that is just a bit better than onboard.
