Gaming is actually defined by whether a game is playable on your resolution. Playable is preferably at least 60 fps, but anything above 30 is playable. Either way any Intel graphics card is not suitable for gaming. Even AMD's 4200 is not good for gaming, but does outperform intel's solution at settings that are playable. A $100 gaming card gives you great bang for your buck and it allows you to play up to 1680x1050 or 1920x1080 with lowered details. You can pick up a 4850, 5670, or the occasional gts 250 which are all relatively powerful cards. For lower resolution you could get away with lower cards like a 5570, but the savings IMO are not really worth it.
