yea, but 4xx and 5xx will fall. Just put -benchmark 180 in claymore to test for a bigger dag file, and see the 480 at 12 megahash in december. the only one keeping a good hashrate from amd is 390 having 29-30 megahash in december. Yea, right...it "IF" eth will go POS...but etc will not :)). 390 also drawing 300W
