Knowing that the monitor is BenQ E 700 series with max resolution 1280 x 1024

You will play all games at maximum settings at resolution 1280 x 1024, but I advice you to buy a HD monitor, and you will still be able to play all games at maximum settings (you will have less FPS, but you will be fine)...
