How to build an average game? What would be a good way to upgrade while keeping within the budget?
I would stay around $ 1200 to build an average computer games. Please tell if there are problems with these specs and what can be done to make it better. In addition, any advice on building a computer would be appreciated.

I did not know if $ 1200 was your target, or more than you wanted to pass, and $ 800 was the target. Well anyway, for $ 800 which is pretty good, although I might recommend getting a 5600 + for $ 80 more, or a 6000 + for about $ 110 more. The graphics card can be upgraded to a 8800GTS 320MB (highly recommended) for about $ 40. And I would like instead get 2X1GB 2X.5GB place on the RAM. It's not very expensive and is very useful to go from 1GB to 2GB.
