Multi Card configs, I spit on them.
Most users would only run 1 card anyhow, Multi Card Configs are still a moot point. My thinking at the time SLI came about, NV thought of saying why not force users to require 2 by making our TWIMTBP games run like crap on a single card. Also no user should require to run a watercooling loop under stock configurations when having multicard configs, only time that should be required is when pushing them beyond stock clocks, just like non factory Air coolers. TBH cards are getting ridiculous in size and heat production. I think cards in a stock configuration should only require a Single Slot Cooler and then if you really want to push then a 2x slot and or watercooling, like back during the days of the Radeon 9700 Pro.
