Hi, Im aiming to build my first PC for gaming. I think i have all the parts together on scan.co.uk, but i was just reading up on the motherboard that i have chosen and it says that it does not support SLI. The graphics card i have chosen is a EVGA GeForce GTX 660 and i know that Nvidia graphics cards have something to do with SLI, not Crossfire. I don't really understand what this means, and because the motherboard does not support SLI i am beginning to wonder if they are compatible. This is my first post here so i don't know if i'm doing it right. Finally i was thinking that in the future i could install another GTX 660 so i have 2 of them, could you please also tell me if that would work if possible? Thank you
