Hello! I am building a new PC with two Windforce 780TI's in SLI on my MSI SLI Krait Edition motherboard. I am looking to get an aftermarket SLI bridge from EVGA. Due to my location I am getting these from pccasegear.com, meaning there is only 3 different sizes available. I am not sure which one to get due to not knowing the length of 1 of my graphics cards to another! Please help me! 😀
