I was digging around looking for a card for my friend and I found one of my old 580's from evga. It isn't the classified version with with the bigger cooler etc... But I'm trying to figure out is there a way to tell how much vram it has just by looking at it or if there would be any labels on the back indicating it? Sadly I'm a parts hoarder and I have collected about 3 of the same looking 580s over the years.
