maybe BF4 on low at 30-50FPS. Corsair builder 550w is going on sale for 20$. Get that instead of antec and get a 660TI and you can run on medium or low.
You should be able to play at 720P and if you want to overclock, feel free. JUST BEWARE OF THE DANGERS OF OVERHEATING. But i dont think you should have that problem often.
