14 DAY TRIAL // The GeForce GTX 780 Ti may be the best single-GPU NVIDIA card in the world (not counting the Titan Black), but the GTX 780 is pretty tough as well.
It is that board that Micro-Star International took and made into a beast of a product, and didn't really have to jump through too many hoops to do it.
Normally, the board has 863 / 900 MHz GPU clocks and 3 GB of GDDR5 VRAM operating at 6 GHz (384-bit interface).
The MSI GeForce GTX 780 Gaming 6G is faster, with GPU clocks of 954 / 1006 MHz but the same memory frequency as above.
Other than that, the board has the same core features, like 2304 CUDA cores and support for all those NVIDIA technologies (GPU Boost 2.0, PhysX, TXAA, NVIDIA G-SYNC, 3D Vision, CUDA, DirectX 11, Adaptive VSync, etc).
MSI didn't just modify the specs though. Besides, it would have been dangerous without some better cooling, hence the Twin Frozr IV Advance fansink. All in all, it will keep the 250W TDP under control, and more easily than the stock cooling module.
Sadly, for some reason, MSI decided against mentioning the price of the GTX 780 GAMING 6G. Alas. This website should see it added soon though.
