I have 2000 files which iTunes somehow decided should be aac and transcoded for me without me realizing it. I want to transcode these back to MP3s as quickly as possible, so I can use them on Google Music.
I have a Core 2 quad core running at 2.9 GHz, and I have a few year old CUDA enabled video card (GTX 260). I'm happy to use either or both to get the job done ASAP. Currently I'm using Handbrake, but I wonder if CUDA might be quicker.
