Is the GTX 670 can be combined with the GTX 660?

Crossfire of HD 7850 and HD 7870 is possible.

Only cards of the same base chip can be SLI'd/Crossfire'd.

The HD 7850/7870 have the same chip, but different clocks so they adjust to the most common lower speed for crossfire.

The GTX 670 and GTX 660 have different core configurations, and as such they can not be combined.

Again to recap, cards with the same Chip (core/shader count ect) can be combined even if they have different clock speeds.

And cards that have different chips can not be combined regardless.

Yup, that's why it's best just to buy another of the same model u already have for SLI, it also looks nicer in the case if u do that. Found that there are different variations of my model number that are VERY different, even tho they look exactly the same. make sure model numbers match for best possible SLI, but really as long as it's the same chip. (660's, 670's, 560 ti's, w/e)
