Its highly unlikely to hit the jackpot. And you are pretty much better off just GPU mining these Satoshi's then going thru the trouble of going with the free faucet.
is it even still possible to GPU mine?
besides you are forgetting about the electricity bill that you have to pay if you decide to mine , and not to mention lowering the lifetime of your graphic card.
not saying faucets are better choice but something like this with a jackpot can be nice if it really is paying every hour and in that amount.
