MSI GeForce GTX 660 Ti Power Edition 2 GB
 

MSI's GTX 660 Ti Power Edition is one of the fastest GTX 660 Ti cards we tested today because it comes with some secret BIOS sauce that enables it to run faster than other cards at lower clocks. This is also confirmed by our overclocking tests where it reaches the highest overclocked performance of all GTX 660 Ti cards.
