GTX1070 cant oc to stock GTX1080.its still 10-15% behind i tested it with 10+ games.Anyway vega mining instructions just killed it.We will not see any vega card in shops because miners or it will be at double MSRP like every GPU on market now(from 1060 up)It really shouldn't remind you of the 290. The 290 was actually (barely) faster than the $500 780, matched the $1000 Titan, and the $700 GTX 780 Ti was only 15% faster. I'm not expecting the Vega 56 to be faster than the $500 1080, and within 15% of the $700 1080 Ti. And it had more VRAM than the Ti, which is opposite this time.
Mining ruined these prices, FWIW.
It looks like AMD is aiming for the Vega 56 to edge out the reference 1070 but not reach the higher card, so I'm not expecting the 290 parallel to hold up. 1070 max OC can match 1080 stock, so I will be curious about Vega 56 max OC. Besides power consumption, it could be a very viable alternative to the 1070. Looking forward to reviews, just out of curiosity.
God i hate miners so much.
