Doubt (m)any will just give you money. Maybe you will get 0.01 from someone
Theres little to no point in buying a GPU imo for a return on its investment unless you want to bet on a rise in BTC value (which at the moment seems very unlikely to me), or wish to partake in many months of 24/7 mining. The figures just dont stack up imo, unless your still a kid when a few $ make a difference.
For example I can make more money with 1 hour of work than 1 month of mining, so I'v been out for weeks now. Still keep a stock of BTC on the exchanges out of interest though
