Thanks to all who replied. It appears to be a popular consensus that I can simply pull out the Q8200 and put in a Q6600 to achieve XP mode capability in Win 7 Pro. If there is any other tweaking or something I need to do I'd appreciate some insight. Looking for the cheapest way to get xp mode working under Win 7 Pro. Would be nice to get a lower power cpu like the Q95XX I suppose but cost is unfortunately a major concern. Thanks again all.
