NVIDIA has been king of high-end graphics cards for past two years. Engadget is reporting that NVIDIA is planning on pushing up the release of their new high-end graphics card GeForce 9900 to July. The reason behind the push is that NVIDIA doesn’t want to take a chance of losing their dominance in high-end graphics card market to upcoming ATI’s RV770 based Radeon HD 4800 graphics card. It is rumored that both the cards will have one billion transistors and more than 512MB GDDR3 memory. This fight to be on top will definitely benefit high-end graphics card consumers.
