Sapphire is preparing an OC edition HD 3650 card with 512 MB of GDDR3 memory. This card will use the same cooling as we have seen on the rest of Sapphire's HD 3650 series.
The card has been pixelized and we are trying to find out how far Sapphire managed to push this card. The card still features a single slot cooler, like the one seen on other Sapphire HD 3650 series cards.
Here is the picture, and we will update the article as soon as we get some additional info.
