Just showing that NVLINK (SLI) actually fully scales and that with the right settings you can get the most out of it too. All games running in 4K ULTRA settings and some scaled even higher at 6K. Games recorded using THE SAME COMPUTER using the GRAPHICS CARDS in OBS with NVENC 4K at the same time that I'm playing to show you how far you can actually push it.
The performance is actually higher when not recording the gameplay and just playing. I do have my own drivers for some of these games and after careful research and long hours I have been able to fix some of the issues some people have.

At the beginning of the video when is on Hitman and on Shadow War I had the PC covered by accident and the GPU temps are quite high but I fixed it.

If the 3080 had 20gb and NVLINK the 3090 would not exist. "Creators" would benefits from 3080 sli more than a single 3090 anyway since software like davinci supports it.

notes: English is not my first language. Gameplay recorded sucks but I was more focused on performance testing than anything else.

Total Spent on GPUs: $500 + $300 = $800

Note: keep in mind that this video is encoded 4K24 because I used my Sony A6400 for part of this video and it doesn't support 4K60 so the timeline had to be set to 24. I will upload the gameplays separately encoded at 4K60 so you can see the motion smoother.
