Exactly as it states above. I want to mine other currencies, not BTC. Paying 13k for a miner that you will probably never break even with doesn't make much sense to me.

If I said money was no issue, what would you recommend? I plan on purchasing the best hardware to retain the most profits.

I followed this page: https://litecoin.info/Mining_hardware_comparison, and it shows this to be the best graphics card for mining: 7990, HD7990-6GD5

Is this the best at the moment on the market? If so, can I use this to mine coins such as Dogecoin?

EDIT: I misread the post and thought the user was after DodgeCoin.

I have also looked into this, and also found sites where there is quite a big profit margin.

However, you would probably want to find out first if you would have to pay tax by doing this. Here's what I've found so far,

If you're from anywhere else then just search for it, you're more than likely to find it here than any other BTC related forum.
