The launch of the Nvidia GeForce GTX 580 came very fast, and while the card performed exceptionally well all around, some people were disappointed by the SLI performance that it had to offer. In some cases the GTX 480s in SLI performed better than the GTX 580s in SLI. Some of these problems were caused by the the hard launch and premature drivers that Nvidia released, but is the same still true after 3 weeks? When we first reviewed the Nvidia GTX 580, we were using the ForceWare 262.99 drivers, but Nvidia reecently came out with the ForceWare 263.09 drivers, which could have some performance increase over the past 262.99 driver. We'll go into more detail about that in the following pages. When the GTX 580 launched, most manufactures were not able to come out with their own overclocked versions of the GTX 580. ASUS was one of the few manufacturers to have factory overclocked cards with the launch: the ASUS ENGTX580 Voltage Tweak. It is a bit ridiculous that the core speed on this card has only been raised from 772MHz to 782MHz, but ASUS claims it produces about 50% more speed, higher performance, and greater satisfaction. We'll put that statement to the test in our overclocking section, and we'll also have some numbers for certain benchmarks.
