Well it's my understanding that GC in Pro 2010 is just a check box that twiddles the node settings, that's point and click. I don't have Pro2010 and if there's more to it, like you have to have an understanding of Math to get it to work in Pro2010 then it's not much of a selling point.

I don't mean to be facetious but I get the impression that it's the latest toy and everyone who doesn't buy the toy is lame.....all of a sudden:)
