What is problem? I have Strix 470 and it's pretty lovely card, very stable and cooling is the best I saw, only no heatsink on memory... Maybe the con is Elpida memory type, but 4GB version is not using Samsung one very often...
I ordered another Strix 470 for testing with performance timings so I hope it could be even better.
Now I'm getting around 700H/s on XMR.
