Opening up to the third gate is most definitely NOT more than enough to take Neji out. We know this because, Neji doesn't even activate his Byakugan until some point between the third and fifth gate, indicating that his normal awareness was enough to follow Rock Lee's movements. His Byakugan was able to follow Rock Lee still with the 5th Gate open, so all he has to do is block Rock Lee with Kaiten, Air Palm, Gentle Fist Technique: Body Blow, etc, until Rock Lee's body gives out. If that happens, it's over for Rock Lee .0001 seconds later, since he needs a cool down period.
