Good Games For My PC

So, I bought a PC with an AMD E1-1200 APU Radeon HD Graphics 1.40 GHZ and 3,70 RAM. Believe it or not, this gear is enough to call an excellent gaming device! I can run Red Faction Guerrilla (Low Settings), Dead Space 2 (Low Settings) and Far Cry 2 (High Settings!) plus Dragon Age Origins (Low Settings). I can run a lotta recent games, as long asI put em in the lowest resolution and low graphics. But, my PC isn't high tech. So I would like some good suggestions of games that run on this device.

Sorry, but all questions regarding what games to purchase have to be asked in the official Game Recommendation Thread stickied at the top of this board.
