Sure, I agree. I just think the impact is less, since e.g. computers are optimized for C (there's special instructions for manipulating C-like stack). I think of more importance is the concept of registers, which C mostly abstracts away - definitely useful to know, but probably less performance impact than pointers vs. objects.
