While I hear generally about garbage collection causing dropped frames. I've had this happen to me in HTML5 land. I haven't heard about it as much with Unity, that C# was fast enough, and the under the hood pieces are C++ anyways. Perhaps I'm reading the wrong channels :). I'm curious if your game project is 3D, and what sort of intensity you tend to have with it.

It depends entirely on the details that affect the GC. The biggest factors are the size and structure of your heap data. If the game uses a lot of memory, the GC will try to collect more often. If the heap data is large and graph-like (lots of refs to refs), it takes longer to walk.
