I wonder if a dual core processor would help out in this matter? I think that may help but only slightly because the FSB may not be able to handle it, even if it was a dual 400 Mhz FSB. Yea, why would anyone want a dual core processor, when many people have an aged second computer (PIII) kicking around which would do a decent job in hosting your second application. Don't get me wrong, dual cores will find its place in the industry (probably servers and embedded applications where circuit board real-estate is like living in downtown Manhatten - a premium). This may explain why WoW does not support built-in skype conferencing support ;) - the load on the server would just be immense. In anycase, I think your system must be pretty awesome, if it could handle a 3-way conference call AND still play WoW. As typical customers, we always want MORE :D.
