TheFakeMrSneaky wroteLike the title says... I have never used SLI and I have always heard it isn't worth it. Was it worth it in the past? Do you think it will become a thing in the future? Maybe now it's not worth it because one card can run 4k for the most part but maybe in the future when there are 32k monitors O.o lmao I guess on a serious note the graphics cards will just get better...
It depends on the use case. SLI is impressively garbage in most case scenarios and the reason was due to technology advancement. Main problem being you can't have something like a 980 2gb card paired into a 980 ti 4gb card. So it was incredibly and still is expensive and your performance is a lot less than you'd expect, they run hotter if you're not using water cooling too, so louder and hotter pc/room. SLI also has problems with stuttering because the frames are getting split up between the two cards. It didn't really help either that AMD and Nvidia essentially let it die and that has it's own reasons.
For gamers especially low end gamers who are getting 2gb, 3gb, and 4gb cards there's the issue of wanting to have better graphics and the reality SLI didn't give that doubled memory and only half of the performance of the second card. Which then came down to the reality of why buy a second graphics card if you don't actually get one?
BUT NVLINK on RTX cards... different story. Being the fact that with NVLINK you get the actual performance you always dreamed of. So if you wanted a 2060 NVLINK setup that could actually face up a 2080. You can.
The reality for 4K gaming though is still not an easy to swallow one, sure a 980 Ti can do 4K, sure... At what fps and what resolution? 4K gaming is awesome (depending on the game) but it comes at a cost of your PC's heat and sound, as well as your fps. If you're like me 4K gaming with World of Warcraft in a raid or battleground, it's cool but... why? In something like Forza, it's down right unreal.
Coming from someone with 3 monitors and a 2080 Ti, 4K is awesome, do I play in 4k often or a lot? I literally only play World of Warcraft in 4K because any other game has issues, be it in scaling, text becoming way too sharp and small to read, 60 fps is not something I'll ever enjoy again, or be it just the actual heat coming off my PC mind you I have 2 360 radiators and yes my 2080 Ti is under water. It's hot in topeka. I'd love to Black Desert Online in 4K in Remastered Ultra, but that is actually going to require me to have a 9900K or 3950X and another 2080 Ti... /shrug.
