The ASUS EAH4890 HTDI/1GD5 has a Radeon HD 4890 GPU at the heart of the graphics card, but you couldn't tell by looking at it. The EAH4890 HTDI/1GD5 has been designed by ASUS and utilizes features like Super ML Caps, a six heat pipe cooling solution, and higher clock speeds to improve gaming performance. This is unlike any video card you might have bought a couple years ago.

Not only should it perform better, but it also looks better since it is no longer a cookie cutter Radeon HD 4890. What's that, my friends? That is a real heatsink. ASUS did not prance around with this one; I believe this heatsink could have handled the notoriously hot ATI Radeon HD 2900XT and asked for a second helping of heat. It has been a while since a "stock" heatsink has impressed me as much..."
