Got scammed because I'm dumb and clueless should I sell it for dirt cheap or enjoy it while it lasts?

I bought a used RX 580 8gb because I thought it was cheap, turns out I overpayed by alot and the card was a chinese card (SOYO) that was 2048SP (way worse than an actual rx 580) I was scolded by everyone because I bought for more than it's worth and they told me it breaks easily and I should resell it ASAP, now I'm kind of scared if I keep it it will break and I lose even more money

should I sell it (and my whole computer since I can't afford another gpu) and since rtx 5090 is releasing I wait a few months if anything goes cheaper or enjoy it and risk it breaking
