The long awaited new Fermi chips are on our doorstep from NVIDIA and the battle is on again with AMD. Anandtech have a great review of the current state of play, with the new GTX480 and GTX470 being put through their paces along with the 5870 and 5970 (plus the dual card configs as well).
Apart from learning the ins-and-outs of the technologies and how we got to this point (think delays) we get lots of graphs of the cards in action, including Crysis Warhead. While I am seriously looking forward to seeing the new NVIDIA GPUs put to some rendering and analysis calculation crunching, as real-time graphics solutions they are rather underwealming. They are fast, but we had fast with the GTX295, maybe we can believe that some 'tweaking' will give us the performance jump we should get from a new series.
