I'm currently running 7 cards
the 7970's go for about $450 a pop
You join a pool to get a steady payout
so, like 5k on cards, say another 5k on setup 5 rigs (2 cards each) so 10k investment pays 1 bitcoin per week? and $120.00 per bitcoin(?) means $120. x 52 weeks=$6240 minus electricity? means like i make 5k from like 10k investment (+ electricity?) or im missing something?
thanks for the answers... much appreciated!
