The i3 530 is a good cpu but you need a discrete gpu for good gaming performance.
Empire Total War requires a pretty good card.
For example my friend has a Dell XPS with an i7 920 and the cheapest gpu offered at the time for his build a GT 220.
He wasn't happy with its performance on Empire and replaced it within a year with an ATI 5770.
And it runs Napolean with no problems as well.
The Total War series have always required a decent gpu.
btw if you're referring to a specific gpu the link provided doesn't work.
