Is there any real reason you wanna step up to Mavericks? As always IF your system runs well now with 10.8.5 which was the best OS ever for us and soo many others I would stay there as long as humanly possible BUT if you need to goto Mavericks for a reason it would be just fine.

Mavericks 10.9.5 was actually as good or slightly even better than 10.8.5 with HD10/HD11 so make sure you have PTHD 10.3.10 latest version and it should be a really stable rig if optimizations are done according to Avids recommendations.
