Could you share that insight? I think Anton is referring to the fact that on a 4-way cpu machine with HT enabled you basically have an 8-way smp box (with special conditions) and so if 4-way machines are becoming more popular, making sure that 8-way smp works well is a good idea. At least that's how I took it. -- "How can I not love the Americans? They helped me with a flat tire the other day," he said. - http://tinyurl.com/h6fo
