This card called Dark Knight is the new product of ASUS. This is a GeForce 9800 GTX+ with a four heatpipe Dark Knight cooler.
The guys at Bjorn3D have reviewed Asus’s Radeon HD 3870 X2.
Read the review HERE.
The performance of this card places it in the middle of the pack just under the 8800GT and above the HD 3870 and 9600GT. You can run many of today’s games with pretty good performance levels. Once you enable AA, the situation changes and this card suffers a pretty big hit.
