Are there any benefits to using a C# method group if available?

Question

When dealing with something like a List you can write the following:

list.ForEach(x => Console.WriteLine(x));

Answer 1

Yes; the first actually can cause an unnecessary extra, interim call to happen; passing x in to a method that simply calls Console.WriteLine(x); You don't need to do the first one because Console.WriteLine already is a method which matches the signature that ForEach is looking for.
