You only need the card's serial number.Yes someone will, but you need an AMD card to redeem I think.
Also the 580 pulse is up for $170 without MIR right now.
Right now I have a 580 pulse plugged in, if there's any test you'd like me to run let me know.
If you are that stingy for 20$, perhaps you should skimp on some stuff But honestly, if you want to sell the codes and all, go ahead if you think it will be worth it, but heads up that because of keys online being sold dirt cheap you won't profit much if any and you might not be able to give all codes away so check their details first. Also, if you can give them away, might as well directly trade them for a key for World, just saying...The problem is that I don't actually know if a 12-14% boost in performance is worth $20. If it is, then I'll gladly swap out.
Edit: I checked the XBOX Game Pass for PC that comes bundled with the RX 590 and nothing on the games list appeals to me, so they could give me a lifetime subscription and it wouldn't matter. However, if I am able to just sell the redemption code or whatever to someone else for like $10 and then the Devil May Cry game that also gets bundled for another $10, then I guess it costs the same as the RX580. Would anyone actually buy it though?
