I am super late to the party, heard about bitcoins a few years ago but was younger so didn't pay much attention to it but here I am now and cannot decide what to currently mine.
Better late than never.
either Lite coin or Bit Coin.
I would recommend you to mine Bitcoins as it consumes less power to mine.
And also with the rising difficulty of litecoin it is becoming unprofitable to mine.
Currently have to PCs one with a GTX 285 and the other with a GTX 680, yes i know Nvidia sucks balls for mining
Mining with Nvidia cards are not profitable because the amount of bitcoins they mine does not cover the power they consume.
so i am looking to pick up a 6970 specifically for mining.
Good luck with your venture.
