Review: NVIDIA GTX680 SLi Review and Benchmarks

Martin wasn't happy testing just one GTX680, he wanted a second to really push the performance

Witcher 2

Witcher 2Witcher 2

For the last game I’ve opted for Witcher 2. I was a massive fan of the original and think that the developers are a welcome sight for innovation in the industry. Witcher also happens to be a game which I consider to be one of the most visually impressive released. When the game first released, I found it to be the best looking game out, although it was quite the GPU hog when uber sampling was involved.
For my testing I ran the game with the “ultra” preset, although I disabled uber sampling. The game was running at 1920x1080 full screen. Given that this game is a DX9 title, I’m very impressed with the visual quality; I can’t help but wonder if they’d been able to make the game more efficient GPU wise if they’d opted for DX11 to recreate the same IQ.
Here are the results of the GTX680 SLI compared to the GTX 680 ;

Firstly the minimum frame rate looks like quite a fluke, a momentary dip, could be down to drivers. Again this is a game where I find the scaling to be quite unimpressive, without even thinking about it you can see it’s about 50% scaling, it’s a welcome improvement, but you likely wouldn’t notice the difference between the single GTX680 and the 680SLI, however one thing I will mention is that with the GTX680 SLI you’d be able to turn on uber sampling and get a playable experience, but would that ever be worth 800 quid in GPU?

Average FPS Scaling; 51%
