UBIQ is a really great project, but I think there are many other projects like ubiq with greater popularity.
In terms of mining - there are a lot of cryptonight-heavy coins, which are insanely profitable to be mined and RX580s are top-notch cards for this algorithm. If you are an ETH believer, you can always mine other coins and buy ETH afterwards. It should yield you 2-3$ more.
That's at least what I'm doing
