Im posting this after reading this http://www.anandtech.com/gadgets/showdoc.aspx?i=3034&p=1 Already some current games are pushing the 2 gig address in both usage and virtual/kernel. As new games are becoming more and more sophisticated, we are reaching this limit. DX10, even in the patched games we have now, uses more resources than their DX9 bretheren, so it only seems to me this is going to be a problem. Maybe gaming will be the thing, along with media apps, that brings us all into true 64 OSes. This may explain odd crashes in certain games.Your thoughts are welcome
