Silent Army 5 is beating claymore now. 80 sol/s on rx 470 4gb and low CPU/PCI-E bus usage. Hope Claymore v5 comes out soon because I like his mgmt features.
Yep, I have the 8GB card and only getting 60 on claymore...
I get ~68 stock 470 8GB, and ~74 stock 480 8GB. Best to use -i 0 on Polaris, speed varies more, but faster on avg than -i 2. Huge difficulty spike, hopefully it adjusts. Claymore speed improvements are fast and furious though!
