hi i ordered Vega56 yesterday, this is my first AMD card since 7xxx series so i have some questions. I read that this card can be undervolted and by doing that you get less power consumpation and better performance? Is that true? and if it is is it hard to do undervolt? Also is 550w 80+ Silver GPU enough for vega56? i think i got good deal on it, i got it for 313$ new one with 3 years of warranty, in my country the cheapest rtx2060 (non super) is 414$ or 418$ for rx5700 (non xt), used gtx1070ti wit only about 1 year of warranty is also around 300$, what do you guys think? tnx
