NVIDIA GeForce GTX 275 896MB
 

This product fits between GeForce GTX 260 and GeForce GTX 285 in terms of performance and price. As we have already mentioned, the new card has been designed to oppose RADEON HD 4890, the most powerful single-GPU card from AMD. This corresponds to the $260 price tag -- more expensive than GTX 260, but cheaper than GTX 285.
