The N210D3-1GI features gold plated, which is durable large contact area connectors have been used for optimum signal transfer between connections. NVIDIA PhysX is the next big thing in gaming! Delivering physics in games is no easy task. It's an extremely compute-intensive environment based on a unique set of physics algorithms that require tremendous amounts of simultaneous mathematical and logical calculations. The best way to get real-time physics, such as explosions that cause dust and debris, characters with life-like motion or cloth that drapes and tears naturally is with an NVIDIA PhysX-ready GeForce processor. NVIDIA CUDA technology unlocks the power of the hundreds of cores in your NVIDIA GeForce graphics processor (GPU) to accelerate some of the most performance hungry computing applications. The CUDA technology already adopted by thousands of programers to speed up those performance hungry computing applications.
