Yes, it can be crowded in August, but - for example - Schynige Platte: if there are many people who want to go up (and/or down), they just put in more trains. There may be lines at gondolas, especially when the weather is fine everyone wants to go up (and I can't blame them :-)). To me it's never been a problem and yes, sometimes you will have to wait a little, but they do everything they can to get people where they want to go.
Have a nice trip!
