Gigabyte GXT 660 Ti OC

Product Number: GV-N66TOC-2GD
Warranty: 3 Years (from manufacturing date)

Gigabyte’s last few cards from the current generation (both NVIDIA and AMD products) have met with some huge success in our reviews. Their GTX 660 Ti OC, with the second highest clock speeds in this roundup- certainly has what it takes to compete with the best but to many, their warranty may be a bit confusing. Instead of starting from the date of purchase, Gigabyte’s coverage starts from the day the card leaves the factory. This means you may never know exactly how long you card is protected. Nonetheless, a warranty length of three years should cover most people’s needs.

The GTX 660 Ti OC uses a WindForce 2X heatsink that incorporates what Gigabyte calls “Triangle Cool” technology. Essentially, Triangle Cool uutilizes angled heatsink fins in order to direct airflow and a large copper contact plate to deliver optimal cooling efficiency. Gigabyte also cantilevers out a portion of the heatsink so it covers the PWM section for additional heat dissipation.

This is topped by a pair of lethargic 100mm fans that push huge amounts of air without putting out too much noise. Unfortunately, while the heatsink is extensive and the technology seems to work, the whole affair tends to feel rather flimsy due to the thin plastic shroud.

Gigabyte has used a custom PCB for this card but the PWM hasn’t been expanded from the reference 4+2 layout, albeit it has been upgraded to an all-digital design. We can also see that the heatsink exceeds the PCB’s outer edge by about an inch, making the GTX 660 Ti OC about 10” long.

Output connectors haven’t changed from the reference design and include a pair of 6-pin power inputs and outputs for DVI, HDMI and DisplayPort.
