lol guys. GPU mining is never dead. "There is always a coin to mine". Anyways, yes optiminer is much faster now with v 1.6.0 for R9 models and 280x. I get 385-400 for 390, 220-230 for 380 and 300 for 280x. OF course your results will vary depending on what clocks you are running, etc. But so far it runs good. Which is why I can't wait to see what claymore has...maybe he delays the new version to be sure of beating those numbers, who knows lol.
Personally, I'm not sure optiminer's v1.6 can be beat, because I think it probably represents the best that can be achieved with current (I don't mean new) GPUs. So, while Claymore will likely match optiminer v1.6 in the near future, I'm not so sure he can surpass it.
