There´s a review of the new VIA C3 Nehemiah on
http://www.tecchannel.de/hardware/1148/index.html
It´s in German, but just look at the numbers;) In short: For games, they only benched Vulpine GLMark and 3DMark 2001 SE. But it clearly shows that though slightly faster than the older cores, it is still WAY behind Celerons and Durons. Remember the Nehemiah requires a Tualatin-compatible board (or maybe just some stack of adaptors? )
