wen Asic dominate Scrypt the price of GPU will Crash !take this in Mind.
This is already happening.I bought a used Radeon 7970 in December for $350 USD off ebay. Just yesterday I sold a New In Box R9 280x for $275.
This is happening for 2 reasons:
1> ASICS are already here
2> Nvidia's Maxwell architecture is better than Radeon in terms of cost vs performance
Nvidia 750ti cards are about $150 new and will run scrypt out of the box at 265KH on 35 watts! A modest over clock pushes it to 280KH and flashing the bios to boost wattage up to 65 will push the card over 300KH. I bought (4) such cards and put a pair into two separate systems. With modest software OC, I am over 6.5MH with Groeslt and a whopping 180MH with Fugue - from each 2 card system.
My buddy built a 4 card system and he is seeing just under 1.2 MH total for script @ 35 watts per card!
Radeon is dead for GPU crypto and doesn't even know it yet. Nvidia has stolen the crown because it is now an energy "sipper".
lol 750ti is at 70 watts on scrypt not 35, but it cant handle new algos. radeon 270x mining x11 about 70-80 watts,
and FYI ati treasure island 20nm architecture is about to hit the market in Q4 2014 or Q1 2015 with 65% performance boost and 40% less power consumption.
