i was wondering if this graphics card will run counter strike source and city of heros
You probably would be able to get away with it. I would say go for a Geforce 6600 GT however. you can probably get one for less than $100 USD. the 6200 really is not meant for gaming, just for people who game very little or not at all.
I wouldn't suggest that card. I have the 6600GT and I can play most games ou right now. I see them for about $100 now.
You can look for some benchmark tests online and see for yourself.
