Hi everybody! What's the difference except for frequency and a set of coasters between GV-N2080AORUS X-8GC & GV-N2080AORUS-8GC??? My be there's some differences in PCB or in Power phases? Or something else? May be somebody give me a link of the GV-N2080AORUS-8GC (NOT EXTREME 2080) review with teardown the card. Thank you!
