Would this be a good gaming PC?

...holy crap, you just keep cranking out awful builds. No. Not at ALL. This is an awful build for games. You keep picking a really crappy CPU and socket 775 is NOT worth buying. The Geforce 210 is a bottom-end pile of crap that can barely play anything. Windows 7 Ultimate is an utter waste of money over something like Home Premium unless you really, REALLY need the extra features.
