Please fill in the gaps for Me.>>>>Mike Some of You Fellows have informed Me that the top commerical versions of some Programs might not be out for a good while. So making the best out of what I've got,(dual 246 Opteron),I still want to try to get the biggest/meanest dog into the fight. How can I get a version of that WS 2003 so I also can use Programs such as Crafty and Deep Sjeng in 64 bit? I'm lost here Fellows,throw me a Life-preserver.I would hate to think I'de has to wait a Year or two before I can got 64 bit.>>>>Mike
