GeForce GTX 760 WinFast Dual Fan OC 4GB Edition is a special edition of GeForce GTX 760.
This edition comes with a custom dual-fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 760 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 980MHz to 1111MHz while its boost clock is now of 1176MHz. The memory clock was increased to 1552MHz.
Furthermore, the frame buffer was doubled to 4GB though this will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product.
Benchmarks indicate a 9% performance boost when compared to the reference card and so this edition performs slightly better than GeForce GTX 670.
