Is there a consensus here, or does it actually not matter? I will be going with x2 in SLI and in a Phanteks Evolv ATX, so space (i.e length of the cards) MAY be an issue once the pump/res is installed. The Founders is the shortest I think, but I don't know how that stacks up against others from an OC'ing point of view as it just has the single 8-pin PCI-E, and if it's actually worth getting something else in terms of real world performance gain?
