So water-cooling is a yes. Overkill is kinda optional due to the wish to have a great looking rig that preforms. However, to the display questions- I would love 4k, though i notice pricing for a monitor is high. I would still love to have a nice 28-34" curve if it all possible with budget. With that said, one monitor is all I wish for. Low input lag and high refresh rate is screaming to me. I do want to get the most out of the games I will be playing.
