Gotcha. Not sure I'd go to the 2070 Super over the Sapphire, not enough performance gain to justify the $499 price of entry.
Then again, I'm thinking the premium for the Nitro+ is also probably more than I'd be willing to pay for it. I'm 2 for 2 on PowerColor success, though, so that brand wouldn't make me hesitant.
Come to think of it, I haven't ever having a new video card I've bought fail on me. Used ones, either, with only 3 exceptions - two dead when I got them (both Nvidia), and one that worked, but had slightly blurry output (back when CRTs and VGA output was still fairly common), also Nvidia. Still, given the number of used cards I'd come across, and the "who knows what the heck the previous owner did" state of the ones that did fail, I'm confident in all video cards in general.
