if you want to warranty cover watercooling and ocing I think evga is your best pick
yea it is "enough" but watercooling is viable when you're on the top, it doesn't make sense spending a couple hundread $ for watercooling your gpu when you could get much higher clocks and stability with a card with a custom pcb for about 50$ more. Put it on water and it will run much faster. With a FE theres just lost potential
not really, they have better pcbs for one=making them better for ocing
