I bet you its a 2.2+ though. The only core 2 duos that are close to capable are 2.2+, but really for 6.5 and higher there is no other choice than i7 ( 3rd generation ) now. Even my i7 quad from 2010 is struggling with some of my newer projects. So I have to say that your claim of "running smoothly" is an exaggeration OR you just don't push Reason to its limits ( maybe you don't need to with your approach ).
