I'd point the GPUs to LTC/FTC/CAP and just mine BTC with the USB.
You can exchange LTC/FTC/CAP on Cryptsy for BTC and you will end up with a larger return that way.
Thanks. I actually was considering doing LiteCoin with my GPUs because of some articles I read.
I assume LTC = LiteCoin, FTC = FeatherCoin, CAP =

. Which of the three would you recommend?
