Which was to be expected but what are the performance gains that PC gamers can expect from it? According to the earlier leaks, Radeon 7970 was expected to be 60% faster than Nvidia’s GTX580. Sadly though, the card is not that much faster. There are cases where the gap between these two cards is almost around 50% and it’s definitely the faster single-GPU, but it’s nowhere as fast as we wished. Oh, and the card can’t touch Nvidia’s dual-chip offer, the GTX590, despite earlier rumors suggesting that it would be almost on-par with it."
