Well... in all seriousness it does depend. You can technically do multi GPU with a Fury X and 980Ti in DX12 games.

If you had AMD cards however... (and called it crossfire instead of SLI...) #fanboyism

True, but OP was asking about SLI specifically.

Cool, look similar to the way Crossfire works.

However, it only works for GPUs with similar PCI IDs. For example, if I have a 760, these are my potential SLI cards:

  

[*]DEV_1180 "NVIDIA GeForce GTX 680"
[*]DEV_1183 "NVIDIA GeForce GTX 660 Ti"
[*]DEV_1184 "NVIDIA GeForce GTX 770"
[*]DEV_1185 "NVIDIA GeForce GTX 660"
[*]DEV_1187 "NVIDIA GeForce GTX 760"
[*]DEV_1188 "NVIDIA GeForce GTX 690"
[*]DEV_1189 "NVIDIA GeForce GTX 670"
[*]DEV_118A "NVIDIA GRID K520"
[*]DEV_118E "NVIDIA GeForce GTX 760 (192-bit)"
[*]DEV_118F "NVIDIA Tesla K10"

Interesting, most of those cards are GK104 but the 660 is GK106, although it might be refeering to the OEM GK104 version.

only AMD allows crossfire for different graphics cards as long as they're in the same microarchitecture, Nvidia will not allow SLI for different graphics cards even if they're just rebadges(gtx 680+gtx 770).

CPU: AMD Ryzen 5 5600X Heatsink: Gelid Phantom Black GPU: Palit RTX 3060 Ti Dual RAM: Corsair DDR4 2x8GB 3000Mhz mobo: Asus X570-P case: Fractal Design Define C PSU: Superflower Leadex Gold 650W

Probably the OEM version, as that does show up as the 660. 

The normal 660 appears lower:

So essentially the same limitations as crossfire (same core = ok).

Isnt the 650 a cut down GK106 or is that he 650 Ti (Boost)?

Edit:

The 650 is a GK106 part.

Seems they're pretty close, according to Wikipedia the 650Ti is a GK106 card, whereas the other cards are GK107 based

 

Still the same architecture, so they pair well in SLI

https://www.techpowerup.com/gpudb/ sais differently.

Search GK106 and you will find the 650.

Edit:

Seems like the GK106 version is an OEM version, all of the aftermarket versions seem to use the GK107 core.

There is GK106 and GK107 cards for some reason?

Let me simply this 

SLI you have to get the same chipset so you could get a ASUS ROG GTX 1070 and a Gigabyte G1 Gaming GTX 1070 and put them in SLI but you can't put a 

ASUS ROG GTX 1070 and a ASUS ROG GTX 1060 together because SLI doesn't allow different chipsets to be combined 

 

Crossfire you can combine a ASUS ROG RX 480 and a ASUS ROG RX 470 because Crossfire allows you to combine different chipsets and a ASUS ROG RX 480 and a ASUS ROG RX 480.
