GTX 670 SLI vs GTX 1080

Hi All,

I currently have a set of GTX 670 in SLI that I've really enjoyed for several years now. I've been considering going to a single GTX 1080.

I wanted to ask the community if they thought the performance change would be much between these 2 setups. It seems like I'd see some fairly good improvements (especially those games that don't support SLI), but is it that much of a difference? I'd love to hear others thoughts.

I'm currently using a i7 3770k and probably will be for the next more few years. Thanks in advance!

A single GTX980 would comfortably have replaced your GTX670s in SLI capable titles. A 1070 appears to go toe to toe with the 980ti.

For single GPU titles, maybe triple the performance? It would be worth it for the architectural and power savings difference alone.

I didn't realize that the performance was that much better. It sounded like it was fairly close. But if would be that much of a performance improvement, then id happily do the GTX 1080.

I forgot to mention that I would be gaming in 1080p most of the time. Down the road I'd look at upgrading my monitor. Does that change anything?

1070 is going to be just about run every possible game at max settings 60FPS at 1920. It should run almost everything at 2560x1440 at 60 FPS as well. A GTX1080 will comfortably hit the upper 90FPS or more at 2560x1440. Just shy of being truly 4K 60Hz capable. (2560x1440@144Hz is just about 5% more throughput then 4K at 60FPS) 3440x1440 at 75Hz is probably also easily within spec for a 1080.

GTX580 -> GTX660Ti -> GTX760 -> GTX670 -> GTX960 (exactly 1/2 a 980) -> GTX680/GTX770 -> GTX780 -> GTX780Ti -> GTX970 ->GTX980 -> GTX980Ti -> GTX1070 -> GTX1080 (1.7x a 980 according to Nvidia)

I think a 1080 is worth it for you. Not much chance of regret. I am having so much trouble selling my 980s that I am going to stick with it until a 1080ti or equivalent comes out and switch back to a single card as well.
