I have come across a GTX 750Ti for £55, is it worth buying this?
What coin would be best to mine with it and how long would it take to get the £55 back?
Really? At the current market, you expect to get back £55 from mining?
I don't think GPU miners now mine only for profit since the profit is really bad. I'm still mining but more like a hobby and to get shitcoin easier than to deal with the exchanges.
