Lol. Well it only cost me about $85 to get what you see in the pic up and running and it's hashing at a decent rate with the GPU limited to 60% power draw, so you tell me.
Yeah, a friend of mine just got a 7850 for $50 (CAD) and he's happily mining, I'm at fault for that since I kept showing him my mining stuff and how much I had made and he decided to jump in!
That's a good price for a 7850. They mine monero quite well for the price. I'm looking to grab a handful of R9 290's hopefully in the next month or so as they're fairly heavy hitters on both monero and ether. Little pricier but the ROI is pretty short.
