Can you game with a Mac pro 5,1?

I do not want to discuss price and value, all I want to know is, if I have a Mac pro 5,1, 2010, 2.8GHz, 8GB Ram and a nice aftermarket HD 7950, I would have a machine capable of playing most current games at virtually full graphics, right?

I have bought one quite cheap and I would like to know if it is indeed a powerful machine for gaming. :)
