Can you? Sure, it's just like a regular GPU.
Will it run games well ? Not really
Will you need an external fan? Absolutely, it doesn't come with a fan but does need one
It has no outputs, how would I use it? Should I just sell it and get another, better GPU for gaming?
You would need something like Virtu to use it for games, and even then it's pretty iffy. The Tesla line is meant for GPGPU, don't try using it for anything else. You can get a EVGA GTX950 for $110 right now, so much as well get that instead.
