Whatever floats your boat...
I've gotten permission to share this video here. I've been running 'Rosetta' on my computer for a few years now, but there are a number of choices as you will see. It involves a free download of the 'BOINC' software, and runs in the background. It does keep my fan running, but is totally worth it. All you need is some free space on your computer. Thank you Kelly of VirtualMP3Studio on LiveVideo for letting me share this.
