Since price started to climb lately, a lot of people start thinking about mining...
To these people =>>> Just DON'T!
It's really a silly idea to even consider buying a GPU/mining rig just before the summer. It'll be hot and you'll just waste so much money on the card(s) and electricity to heat your home even more. Just wait until the summer's over and then check the market and GPU prices again.
Mining in the winter months makes much more sense - you'll get at least free heat as a byproduct of mining.
