1. its almost 2019 and 1080 ti is outdated. old driver, old hardware. I bet its dusty like relic from pyramid.
2. 2080ti quad sli is the most desirable setup and best for gaming setup.
3. 1080 ti is soo slow, and dont buy it, buy 2080ti.. bc soooo slooow.. like snail glued to the floor.
4. rtx 2080ti has ray tracing technology that use fake light to mimic real light. so if you afraid to go outside because of real light, just turn on your 2080ti setup and boom! realistic fake light!
