Question GTX 1080TI SLI

[tlavanway3]

Hello, I currently own a GTX 1080TI and its serving me well ATM but i would like a little more graphical juice for my game, but i dont want to drop 800 dollars on a RTX 3080, so i was wondering if it would be worth it to just pick up another 1080TI for 300 bucks and SLI them? and get the same performance as a 3080. I have everything i need to SLI and my PC supports it, my specs are below

GPU: GTX 1080ti Aorus
CPU: Intel i7-10700k
Ram: 16gb 3200mhz Duel channel
PSU: Corsair CX750M
CASE: Phanteks P600S

SLI support officially ended in January: https://www.tomshardware.com/news/the-end-of-sli-as-we-know-it-nvidia-reveals-new-model

You would likely need a new psu too, regardless of which route you went.

I want to add that throwing a second 1080 Ti in there is not going to get you the same performance as a 3080. SLI doesn't always scale exceptionally well, and how well it scales will vary drastically from title to title, depending on how well it's been optimized for it. Back when I was running two 980 Ti's in SLI, I want to say probably the largest increase in performance I saw vs using only one card was maybe only 50%. Most developers from what I've seen can't really be bothered to support it these days, especially as newer cards are entirely lacking the feature, and current SLI users are in the minority. You may have some luck with some older titles that still had some support for it implemented, but I moved on from SLI when I started to notice my second video card sitting idle most of the time while playing a lot of games, if not outright encountering problems.
