Well it's not for me. My friend owned a 9550, and went to the store and the dude behind the counter highly recommended the 6200 because it had more ram (256).
I am not familiar with the 9550, but I am pretty damned sure it's better for gaming than a 6200.
I don't know how to directly compare those two cards, but keep in mind that the 6200 tc is using shared memory. I guess I would recommend the 9550, but would ask if this pc will be used for gaming, consider a 6600 or x700 or something with the slightest amount of teeth to it.
His card is actually an AGP, so I made a mistake with the TC. Well he's bringing the card back, he's lucky he can get the money back. He's going to take my advice and go with a 6600GT.. which is 3x better at least.
