Me personally, I stick to nVidia cards. I've never used AMD, but I know they make great cards with great performance, but in my books, they have high TDP from what I've seen, and sometimes, high temperatures. Those factors don't effect everyone (they effect me, that's why I stick to green team) but whenever I look around GPUBOSS, AMD vs AMD and Nvidia vs Nvidia are mostly fair, but when it gets to AMD vs nVidia... check this link to finish my sentence: I don't particularly like AMD, but WOW... http://gpuboss.com/gpus/Radeon-R9-270X-vs-GeForce-210
Are there any cases where they are NOT biased? I only remember one case where AMD won by 0.1 score. Other times (like the above example) have no winners declared.
