4-5 for sure, although I'd say the interesting question is which was the biggest leap aside from that one?
For me, after 4-5 it's between:
2-3, mostly because of Nintendo basically saving the industry at that point and pushing game design forward in such huge ways, or
6-7 - not the biggest step up from a technical standpoint, but certainly a period that saw some massive change in game design (motion control, touch-based input, the rise of mobile gaming, the rise of indie games, online gaming approaching mainstream popularity).
