Q:

Fastest way to convert a large amount of FLACs to MP3s

I'm looking for something that can take advantage of my GPU or at the very least, multiple cores of my CPU to convert a few terabytes of FLAC to mp3 (VBR v0) very quickly while preserving all of the tags.
Any advice is greatly appreciated.

A:

Depending on the directory structure (is the data flat?) you could kick of a number of pacpl in parallel.  It does a reasonable job at preserving tags when converting.
It won't utilise GPU, but with some parallelisation you should be able to make use of several cores (disk might become the bottle-neck).
