Will my ASUS H97 plus bottleneck a gtx 1080 or gtx 1070? Just wondering if i should upgrade my motherboard first or not?
It depends on what CPU your are using on that H97-chipset motherboard, what games you are playing, what in-game graphics settings you are using, and at what resolution/refresh rate your monitor is displaying.
If your CPU plugged in the Asus H97 is an
i3-4xxx, then, that CPU won't be able to handle those powerful GTX 1070 and GTX 1080 GPUs without hindering its performance.
If your CPU is an
i5-4xxx, then, you it is unlikely it will hinder those GPUs graphics performance (except in very CPU-intensive games on lower resolutions).
If your CPU is an
i7-4xxx, then, you won't have any problems pairing any of those aforementioned GPUs to reach its max. graphics potential.
The
GTX 1070 is a GPU ideal for 1440p/~60Hz or 1080p/~100+Hz AAA gaming on Ultra/Max. detail settings.
The
GTX 1080 is ideal for 1440p/~100+Hz or 1080p/~144+Hz AAA gaming on Ultra/Max. detail settings.
Actual FPS (frames per second) output will entirely depend on the actual game, environment/scenarios within the game, and the specific in-game graphic detail settings you are using.
The H97 (4th-gen Intel platform) is still a good/powerful platform to use in this day and age. No need to upgrade this as it will be costly for you (buying new motherboard, new CPU, and new DDR4 RAM).
