The GIGABYTE HD6770 Silent Cell is a different take on your normal HD6770, it has no fans but does sport a double wide heatsink.  Sporting all of GIGABYTE’s Ultra Durable components you can pick up this card for a hair under $140; or more importantly for [H]ard|OCP’s review you can pick up two for about the same price as an HD6950 or a GTX 570 if you can find one on sale.  Their testing showed that at a resolution of 1920×1200 the two HD6770’s could hold their own but they quickly fell behind the competition when resolution was raised beyond that point, which would include EyeFinity.  If your case has the space for the coolers and you have an overwhelming urge to play games at a 1080p resolution on a silent machine, then these cards are for you.  Apart from that goal, you are better served with a single higher power GPU.

"Today we’ll find out if two of GIGABYTE’s HD6770 Silent Cell cards can match the performance of a Radeon HD 6950. We were impressed with how this no-fan silent configuration CrossFireX setup performed. However, is it worth $280 against the falling prices of the Radeon HD 6950?"
