This is just probably a personal preference but I am getting the MSI Enthuastic Gaming Intel Z170A LGA 1151 DDR4 USB 3.1 ATX Motherboard (Z170A XPower Gaming Titanium Edition) and if I do sli, (1070 graphic card) will it look better with 2 of the same cards or should I get one of 2 different brands? Lastly, what are the best cards to match the motherboard and which cards are preferred?
