True the 290x was hot used more power but couldn't beat nvidia cards using less tdpThe 290x has NEVER been 50% faster than the top nVidia card with the same power usage.
It was actually a wash with the titan at higher power usage, then slower than the 780ti with higher power usage.
980ti is 50% faster than 290x with the same power, and a MUCH better reference cooler than anything AMD ever thought up meaning it can actually keep cool without deafening you.
