What games could this run?

[TheCheesy4]

Righty-ho. I'm planning on building my first gaming PC in a month or so. Having spent about a month looking around the internet, asking in forums etc., I have come up with the following specs. I was wondering what game they could run on full e.g. Crysis, Company Of Heroes, Metro 2033, S.T.A.L.K.E.R. If not, would it be possible with different parts at the same (ish) price, or with some overclocking?
