So a few replies...
Metroid: for GRIN COIN, the use of GPUs is the only source of mining right now and our 570 16GB card is the lowest cost card that can efficiently mine C31 for GRIN. So there are still some buying GPUs for mining.
Lunobird, I will pass your request along. The 570 is an older chip but a tried and true efficient miner.
Badbart, ASICs are still a ways out and even then might not be as cost effective, especially with the planned branch coming up that changes the mining to C32.
thanks for passing my information along. Nice to have manufacture representatives communicate with the mining community. I think what your doing is a great start, Breaking away from the traditional gaming market with only gaming spec hardware, Theirs such a big demand for specific blockchain gpus that has not been tapped into yet. For your next hardware if you can deliver a product that satisfies the performance needs for blockchain processing. If you can do that convincingly, you got yourself a huge hit. All it needs to be is cheaper and/or faster then a gaming spec gpu. Not much to ask. That simple. I think team green gots you guys beat with their rtx cards and even 10 series in terms of overall mining performance.
Cmon Sapphire you can do better than that. Its cool the Sapphire card can mine C32 in the future but that's betting on one algo and being a one trick pony. It's just makes more sense to get a 1080ti or 2080 rtx and mine grin much faster right now. Or get a vega vii and not have to worry about slow clocks holding you back.
