I would like to know if I can mix a asus rog strix rtx 2080 oc with a asus rog strix 2080 super oc in a NVLink setup? trying to get a higher fps in multiple games with out paying 2800$ for a 3090 or 3080 ti at 2400$ here in Norway
 
Yes you should be able to since the cards are pretty similar and support the same SLI/nvlink configuration. The higher clock speed card will downclock to meet with the lower speed clock however, so it's not entirely recommended, along with the fact a lot of games are simply killing off SLI support since only a minority of people use the feature for gaming. In fact, Nvidia has officially announced that it will no longer provide SLI profiles in their drivers as of January 2021. Any SLI support will have to come from the game developers themselves, which a lot won't bother with for the reasons explained earlier along with it costing more to develop. Also not to mention that it's just a hassle to setup and configure properly etc etc, basically there's a reason it's dying off.

tl;dr, it'll work but it's pretty much a dying feature. Best to just go and spend the money on a powerful card.

Nvlink is not sli as such. Sli uses a master-slave system where one card is primary and does most of the work while the slave acts in a supporting role. Nvlink is a bridge that allows both cards to act independently or simultaneously, both acting as master. Only requirements as such are identical chipsets and ram. Brand or OC setting or naming is irrelevant. Nvlink supports and includes sli functionality, as well as mgpu.

A 2080 and 2080Super use different chipsets, so are incompatible for either sli or nvlink.

Nvlink/sli is functionally dead, nvidia no longer supports it officially, is leaving it entirely upto game devs to include such support. It's biggest technical issue is that in the few modern games available (it's a Very short list now) fps gains are only applied to maximums, fps 1% lows are not effectively also increased, which tends to exponentially multiply the chances of stuttering, frame drops or other irregularities.
