... Pretty sure people will look up the exact same card they have, and not a different one lol.
two identical model of cards can still have differences. not all chips are the same..
Also, most modern airflow and cooling are the same, so it doesn't factor much.
you're full of stuff. there are so many different sized cases, fans, fan speeds, cooling liquids, cooling systems, heat outputs, etc etc etc
If you overclock factory overclocked cards, they will lower performance and give artifacts and what not.
my factory OC'd 580 that I pushed even farther gives no problem and has a bone to pick with you
stop spewing untrue information, you're a moron. door's that way.
