Hi guys how are you?

First off all merry Christmas to everyone, all the best

Can you just solve a little and noob question for me?

I have 2 Galax 980ti GOC Edition, is it normal that the high asic card boost better than the lower asic card? Boost clock is always related to better asic?

And about mounting cards, should I always let the high asic one on top playing with Sli?

Thanks guys
