Raspbmc use 128MB for GPU which, according to many, is not optimal for 512 boards.
If you have a 512 board I recommend to use 256MB (I have ran it on 256 for a long while and was recommended by Dom/Popcornmix from RasPi).
I am almost 100% positive that this will fix your problem.
There are more things you can do as well, such as run GUI in 720 (standard for Raspbmc), lower resolution for fanart, different view mode in library etc.
But as you say, overclocking is probably a good idea for HD content (I run on 1GHz, works very good).
