I am building my first pc, and i was planning on using dual 980 ti's from evga. They are the reference model ones, not the custom cooler ones. I was wondering if you thought that i should water cool them or if i should leave them be. Keep in mind that i am talking about this strictly from a performance perspective, not from a looks perspective. Is there reeally that much of a tangible benifit to watercooling them?
