With a pair of passive 3d glasses you can play games which supports passive 3d.
If you want active 3d with your current setup you need a kit which has a IR emitter that bridges between your monitor and your pc, and you need to have a pair of universal active 3d glasses(shutter), and have to buy the software tridef that has the drivers to run the card in 3d and the configurations for the games, when you have all this, 3d gaming might still not work depending game to game, and 3d gaming is something that varies game to game. There are good implementations of 3d and bad ones, mostly bad ones, just like films where there is avatar, and then there is the rest.
It can be easier switching monitor with one that supports hd3d but good luck finding one, amd does not support hd3d that much and the market of hd3d enabled monitors is nearly dead.
Or you can switch card to nvidia and buy the nvidia glasses coupled with their ir emitter, all will be easier and compatibility broader thanks to community support helix, quality of games in 3d might not differ that much tough.
Imho just get passive 3d glasses and enjoy a few films, if you want 3d wait for oculus rift (or get the dev kit) and possible competition, active 3d has never been succesful, probably with shutter with monitors at 240hz might become decent.
