EDIT: Forgot to mention this BIN file is for 7950 or 280X cards, haven't tried it with any others!

If you're on 14.4 drivers and don't want the hassle of going to 14.6, just download this guys BIN file (I had to modify the BIN filename from 8192 to 8191 as that's the TC I use). I've got a 20% boost overall:
