Benchmarks: GTX 680 4GB vs GTX 680 4GB SLI vs GTX TITAN

Last weekend I tried to see how well SLI scales in iRacing when using separate screen rendering in Surround. I always had a feeling that SLI scaling is not that good in iRacing but since I needed it for other games and SLI was otherwise non-problematic in iRacing, I kept using it.
These days however, I pretty much stopped playing games and now have a dedicated system for iRacing, so I had to investigate this a bit further.

After comparing the 680s and SLI scaling, I immediately noticed how much smoother the single card was, even though the frame rate was lower. Reminded me of my 580 GTX 3GB SLI vs 3-way SLI test in which the 2-way solution provided a much better gaming experience in most games even though the frame rate was lower.

Because of this I had a feeling that the TITAN would provide a better experience in iRacing with about the same performance as the SLI configuration, so I ordered a single TITAN.

And here are the benchmarks:

For the first time since the 7800 GTX days, I'm running a single GPU in my system and I couldn't be happier
Performance of a single TITAN is at least on par with the 680 SLIs but without any of the typical Multi-GPU drawbacks!

Keep in mind, this is at quite a high resolution and the TITAN is known to perform at its best when the settings go up. However, in general I'd say don't use SLI for iRacing and use a faster single GPU configuration instead. SLI might be a good upgrade-path, value configuration and/or over-the-top gaming setup for most games, but not for iRacing.
