It is better, which is exactly why I bought the 3690 i/o 3680. Shop around and there are deals to be found on that chip too. Also note it isn't just clock speed, but QPI that is much faster on the 3680/90. I run apps that need every ounce of power I can get, and all of those little increases add up...until you hit the inevitable bottleneck for your specific machine/app(s). To the extent Geekbench and other benchmarks mean anything, it's been money well spent.
