Provided the drivers work, I don't see much reason for SLI not to work. I'm not aware of many games that are written differently on Linux versus Windows that would remove/keep multi GPU support.
I put my GTX 690 on a Linux system for a short time, essentially combining two GTX 680 cards onto one card. It supports SLI to utilize both GPUs, but on Linux it appears as two separate cards without an option to activate SLI.
Check if the driver is available for that card on Linux. Try launching the Nvidia Control Panel to see if it works.
Yep, the system doesn’t have the card installed yet, so I can’t run tests. I managed to launch the control panel before, and everything seemed fine except for the absence of SLI. It’s not compatible with my setup either. For my brother’s 690, a card would be great if SLI is supported on Linux.
When games aren't built with SLI in mind, enabling it becomes impossible. Most Windows titles are sli compatible now, but when ported to Linux, developers usually add a translation layer to change DirectX to OpenGL—similar to WINE. Instead of rewriting entire game engines, they simply install a conversion tool. Major publishers such as Feral Interactive handle this well. (Search for indirectx) It’s clear the challenges of adding SLI support in ports are significant.
If the drivers are compatible with Linux, I don't see why they shouldn't.
