I'm building a system for myself, and have settled on an rvo2b-ew (the updated r2 with three air penetrator intakes). This question is valid for any very high intake air case, though. With the doomsday clock to the 31st rolling around (and my money coming in next week), I'm still mulling between cards. And that's fine, but the one question is, with a case with such high air flow, how much of a benefit is there really for getting a card with a non-reference cooler? I plan on OCing it/them, and I wonder if I'm not gimping myself looking at reference designs as that case can shed a lot of heat.
