Hello, there are several companies selling cards of different variants using the GTX 1080 Ti, which brand and variant do you recommend? I plan to buy one card first and if needed, add more later. Somewhere I read a recommendation to stay away from the reference edition which I read is also called the Founders Edition. Shall we follow this advice? Do overclocked 1080 Ti performance significantly better? In the past, overclocked systems tended to fail sooner. Not sure if it is worth. I have not seen the motherboard for the Threadripper or Intel i9/X series. Do I have to worry that having a large cooling system on the GPU may not allow me to put several in the computer.
