...imho absolute necessity! i think you won't even get two of them working beneath _without any space inbetween_ yet 4 stacked together like a 1.5kW heat generating massive brick - they surely would melt down within seconds :)
i had massive problems getting 2 gtx 560 working while mounted within 4 slots, and afaik others, that use air cooling with such a
setup, run at temperature limits too.
and if you'll ever go that way, you have to have a look at the nozzles of the watercooling block. some blocks - or cards like the pov with stock watercooling - have the nozzles aranged in a way a multi-card setup wont't be possible; at least from what it looks like...
