My current PC has a EVGA GTX 1080.. 8gb, I think. I'm considering upgrading and I haven't had any experience with the 2080ti. I was wondering what the general consensus is for a single 2080ti or a 1080 SLI setup. Would it be worth it to upgrade to a single 2080ti or an SLI setup? And it's not possible to do an SLI setup with a 2080ti and a 1080, right? I'm still learning a lot about building.
