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.
