The site did see some potential in the system, however, saying that it's very possible that NVIDIA will be able to address many of the problems in upcoming driver releases. Slightly more positive about the config were the folks at HotHardware, who were pleased with the performance, and seem to have been more satisfied with the setup's ability to scale with various applications than PC Perspective was. On the downside, they did admit that the system didn't scale well for everything, and there is of course the little matter of price (about $1,200), which will likely be pretty hard for even the most die-hard performance junkie to justify.
Bah I didn't see that this was already posted. Sorry
