All-Around Best GeForce GTX 670: Gigabyte N670OC-2GD
Gigabyte's card is quiet at idle and not too loud under load. Its cooling performance at idle, during normal desktop work, and during gaming is even better than Asus' card. It ties Zotac's effort for the lowest temperature at idle, but achieves its goal at a mere 20% fan duty cycle. When we configured it to cool our card down to 70°C, its sound level was still acceptable.
This is the slimmest card in our test, it weighs the least, and is even suitable for SLI configurations on motherboards with a just a single-slot gap between 16-lane interfaces. Unfortunately, that's pretty common. Although the N670OC-2GD doesn't include the highest overclock, it's currently selling online at the same $400 price point as completely stock reference cards. And that's with the Windforce 3X cooler. That combination cannot be beat.
EVGA GeForce GTX 660 Ti Superclocked is a copy of the reference card with a slightly overclocked GPU. We have a lot of respect for EVGA, but, unfortunately, the company loses this round by taking the last place in our competition. Noisy and relatively inefficient cooler, simple reference PCB and mediocre results in our overclocking and performance tests determined our decision. Maybe this is the reason why EVGA has already discontinued this product, replacing it with a more interesting FTW modification.

Gigabyte Windforce 3X seems like a good option for OCing with it's efficient cooling system. It also has higher stock clocks over the similarly priced Asus DirectCU II Base model. It's unlikely that I would consider overclocking to be honest since I'd like to keep the card going for as long as possible. I guess I'll have to bite the bullet and go with Gigabyte.
