Yeah, there must be a calculation glitch. If you notice the 1 290x is estimating about 160K ppd. So you are looking at close to 320K ppd.
Though for weird glitches, my hydra setup had GPU 1 report in afterburner that it was 511°C, and running at 200% GPU usage. At that temp, the card would be melting and burning. Didn't get a screenshot but it would have been amusing to post.
