buy a 1070 for $430 on newegg it can get 37MH under ubuntu at 145w, for me it's worth the money at that rate
the 480 will most likely be the same in term of watt per performance, inital cost will also be around the same on the performance ratio
I can't really afford that, I was just wondering if the hardware I'm going to buy is strong enough to mine. I guess I'll use it only for gaming, it's a good card and proccessor although.
