But that comparison is meaningless.
Who is buying a 1080 to under clock it? And to compare it to a high OCed 980 TI? Really?
Its like buying a BMW M3 2016, limit it to 20km/h, and claim a 1960 VW beetle is faster, so you should not buy a M3. Its just... why???
Though do take in mind that if you under clock the 1080, it takes much less than half the power of the 980TI, which is the whole reason to under clock a card. If you want to make the 980 TI to take a lot less power, you will not be even close to an under clocked 1080 in terms of performance.
