MSI GTX 760 Mini-ITX Gaming 2 GB @ techPowerUp
 

If you are looking to build a SFF gaming PC or a compact Steam Box, then the MSI GTX 760 Mini-ITX Gaming should definitely be on your short list. It runs quieter than any other compact graphics card we ever tested, yet still has enough power to play all the latest titles at full HD with maximized settings.
