I've had my two R9 270X's in my AMD machine going 24/7 for the past couple of months and I average around 160k ppd, with peaks at 220k ppd. This seems low to me and I have noticed my bonus is always less than predicted, usually about half. my spu doesn't runa client because I OC it. I am still waiting to upgrade MB with new cpu, because at the moment it is my bottleneck. I recently upgraded the ram allowing me to overclock the cpu from 3.2ghz to the 3.3ghz stable. I've seen a few people post that their 970GTX runs well over 200k per day on a single card, this looks nice and I may build another computer with an Intel/Nvidia. When I bought my R9 270's they were 149.99 and I see they are now going for 279.99, almost the same price as a 970gtx.
