ABIT is making a play for the high performance graphics market with a new cooling system that it claims will allow you to push performance of a GeForce4 Ti4200 chip up to the level of a Ti4600. The company has just completed a European tour extolling the virtues of the Siluro GF4 Ti4200 OTES, which will be available on 23rd September, and expects a UK street price for the card below £150, so you get Ti4600 for about half the price.
It works like this. OTES (Outside Thermal Exhaust System) uses some of the ideas from notebook cooling systems, although it clearly doesn't steal them wholesale, because it's patent-pending. It uses a vacuum to seal the Ti4200 on a copper base, then a 7,2000 rpm fan to cool the system. This of course just gives you a cooler card, so in order to actually deliver the extra performance Abit is shipping overclocking tools with it.

The main advances of Pixel Shader 3.0 and Vertex Shader 3.0 is that they will have an almost unified instruction set that will reduce the necessity for learning one instruction set each for Pixel and Vertex Shaders.
The new Pixels Shader will get access to Vertex Shader branching and control flow instructions while at the same time the new Vertex Shader VS 3.0 will give access to general texture fetches and some information associated with the colour and the Z Buffer.
From a conceptual point of view it's this unification of instructions that could be of great importance as it will allow a programmer to think of the VPU as a generalised processor -- similar in many ways to a CPU which handles graphics operations.
