@nelly i had horrible experience with my sli setup because of my motherboard ..the pci slots were too close, My cards couldn't breathe, But i always had great experience with nvidia's multiple gpu cards..9800gx2(Gigabyte) and now 690(Evga), No headaches, No over clock, More breathing room for cpu cooler its just perfect for me..im pretty sure you wont run into any issues with sli coz 700 series have better cooling than 600 series..But dont just take my opinion wait for the others and please dont rush into buying anything until nvidia release the two new cards, im pretty sure nvidia will drop the price or make slight adjustments for rest of the cards.. to make these two fit in..
