It's a Radeon HD 7660D(Not great but i get 15Mh/s with it). My electricity is free and it's my spare PC which means i have nothing to lose.

And btw, what would i do with LTC? Can i exchange it for real money? And also what's the difference if i mine BTC or LTC, BTC is worth a lot more than LTC so are you saying i get more LTC than BTC mining?

Thx and sorry for the freaking 2000 questions doe haha
