NVIDIA SLI
Reddit take
AI summary of the Reddit excerpts below — not a quote
NVIDIA SLI is widely regarded by the community as an obsolete and problematic technology. While it historically offered performance gains for multi-GPU configurations, it is now characterized by a lack of support from both NVIDIA and modern game developers. Users frequently report that the technology is finicky, unstable, and incompatible with modern rendering techniques, leading many to advise against its use in contemporary builds.
Pros
- Historically provided performance gains of 50% or more in specific supported titles
- Manual configuration in the NVIDIA control panel could occasionally resolve compatibility issues in older games
Cons
- Almost no modern games support SLI
- Incompatible with modern game rendering techniques
- Frequent stability issues, including system freezes even during basic tasks or benchmarking
- Minimal performance gains relative to the high cost of a second GPU
- NVIDIA has been actively phasing out support for several years
Caveats
- The technology is effectively dead for consumer-grade gaming and is no longer a viable path for upgrading modern systems.
Best for
- Legacy gaming builds using older hardware (e.g., GTX 900 series or older)
- Enthusiasts experimenting with older titles that have native SLI profiles
Avoid if
- You are building a modern gaming PC
- You are using a modern GPU like the RTX 3080 or newer
- You prefer a stable, plug-and-play experience without constant troubleshooting
This summary uses balanced time weighting with about a 6-month half-life. The evidence is older (median age of 225 days), which reflects the legacy status of this technology.

I had SLI’d 285s, which eventually got warranty replaced with 560s by EVGA (who really were the GOAT). I then upgraded to a pair of 780s. From all those years rocking SLI, I found it was usually possible to fiddle with the settings in the Nvidia control panel to get things working reasonably well. Performance was definitely at least 50% higher than a single card in the games I was playing though.
Hence why SLI and Crossfire are no longer a thing for consumers, because they really do not work for modern game rendering techniques.
The reason SLI cannot work is because SLI inherently doesn't really work to begin with. It could be any number of reasons, it's finicky on the best of days and unusable on others.
Welcome to the world of SLI, where you discover 1 issue at a time why SLI no longer exists.
You can solve it by not running SLI.
What you’re thinking of is SLI which or cross fire which are NVIDIAs and AMDs support to use multiple gpus as one, which even if the 3080 supported SLI (which it doesn’t) almost no modern games support it.
Nvidia has been dropping SLI support for years, so you might have to go back pretty far.
I have recently built a pc with 2 gtx 970 and tried to operate SLI on it. Whenever I run furmark and even steam, the computer freezes . There's still mouse movement but noting could done with it.
Crossfire/SLI is a tech that never worked properly anyway. Let it go.
It was cool and all, but SLI sucked. The gains were minimal, not all game supported it, and even the ones that did often had issues
