So I can't decide R9 280X with aftermarket cooler or R9 290 with stock cooler? Is it a huge performance gap between 280x and 290? I heard, that R9 290 just unusable with stock cooler, cuz it runs too hot and too loud. I don't mind a sound, but does the heat will damage the card? Or should I just go for R9 290 and underclock it?
