How would his laptop perform in games?

My mentor gave me a HP laptop with dual drives, a intel centrino duo, and a GeForce GO 7600. Question is, how well will this get me on all low settings maybe med on 1366x768? I plan to use this for when I travel and stuff. It only uses a 32 bit system, or so I've heard.. But anywho, In games like gmod, league, payday 2, how far will it get me?
