Um,, not totally a bad card. While it will never be a top gaming gpu, it can play most older games well. It replaces the older ati2400pro/x1300/ati9600 budget card and has about the same power. So you need to try playing games from the ati9600 era.
Any game that calls for a ati9600 or geforce 3 or 4 or geforce 6200 or 5950 should run fine.
Good games to try are games like midnight club II, call of duty 1, 2, serious samII, HL2 (older valve based) games, unreal tournament 2003 or 2004,
quake2. bloodrayne2 and Will rock.
I would try playable demos first and see what runs.
