The idea with CSS/CS is that you turn the res and details down to get the fastest play possible - but with these cards there's only a 1-2fps difference between them at lower settings. So in terms of fastest play maybe neither has won.
Higher setting are used when you play for fun - even then there's not much of a difference it seems.
