Review: Gigabyte GeForce GTX 660 Ti OC (GV-N66TOC-2GD)

Overclocking

Gigabyte's out-the-box speeds are handy to have, but we know the GeForce GTX 660 Ti core can go further, and the fact that Gigabyte opts not to overclock memory as standard leaves us a good amount of room to work with.

With a slight bump in voltage, we had the base core clock up to 1,130MHz and memory up to an effective 6,660MHz in no time.

The overclock gets an extra 10 per cent out of the GTX 660 Ti WindForce OC, but that isn't enough to trouble the still-excellent GTX 670.
