ASUS Matrix GTX 580: Official Teaser Pictures, ASUS GPU Tweak
Asus has released two teaser pictures of its upcoming ultra-high end graphics card: the Matrix GTX 580. Based on a GF110 GPU, this GTX 580 packs 512 shader processors clocked at 816MHz (Platinium model) or 782MHz (standard model), 1.5GB of GDDR5 memory and has a 3-slot height house-made VGA cooler, certainly derived from the DirectCU II that cools this GTX 570. An impressive 19-phase VRM will make this card the favorite toy of extreme overclockers.
