I don't think it's a matter of trying to convince you, but a matter of how big your pocketbook is and how much you really want to spend and what kind of return you will get when you go to sell the new Titan(s) X you purchase.
I was able to get $750 each for my Titans when I sold them and purchased my current setup.
While I appreciate the truth in what you say...No, I need someone to convince me...because I am just one foot on the fence and unconvinced, buying new toys is always fun, but the numbers to me are... meh.
