MSI GTX560 Ti 448 'Power Edition' Review @ Vortez
 

NVIDIA have long had a marketing strategy to release cut-down versions of their high end products. The product we have today is one such item. Based on the GF110 core, the same GPU that's used in both the GTX570 and flagship GTX580 graphics cards, you would be forgiven for believing you have a GTX570/580 in disguise. There are however some inherent differences between the three cards.
