Curiosity question here. I'm thinking of grabbing a 2nd GTX 570 for SLI - would cost me about $150 new - and having dual monitors would it better to have both monitors on one GPU or have one monitor per GPU? My last SLI configuration on GTX 280s I had both monitors on one GPU....I never tried one monitor for each GPU. I looked around online and I haven't really found a useful answer. Anyone have any info or first hand experience?
