So guys what's the deal with SLI how well does it work on the new NVIDIA cards? Dual card setups used to be absolutely plagued with problems. Do most games support SLI these days or are they few & far between. The reason I ask is I've been told a dual card setup is practically a minimum requirement for running games on a single hi-res monitor (2560x1600/1440) is this true & is there anything else I should be aware of when building a dual GPU system?
