techPowerUp posted a review on the ASUS HD 7970 Matrix Platinum 3 GB
ASUS has increased clock speeds to 1100 MHz. That is 50 MHz more than the GHz Edition and higher than any other HD 7970 card, including the MSI Lightning. Memory clock is, with 1650 MHz, also higher than any other AMD card.ASUS HD 7970 Matrix Platinum 3 GB Review
The card comes with a powerful triple slot cooling solution and adds many features for hardcore overclockers like support for VGA Hotwire, voltage control, and three buttons for direct GPU voltage control. We also find voltage measuring points and a Turbo-fan button to set fan speed to 100% on the card.
Price-wise, the HD 7970 Matrix comes at $480, which is quite a price increase given AMD's recent price drops for the HD 7970.
