Do the Core i5-12400F and GeForce GTX 1070 bottleneck each other?

Yes. At 1080p (1920 x 1080) the GeForce GTX 1070 is the limit and holds the Core i5-12400F back by about 38.9%, for roughly 41 fps on High. High. 41 fps is below the 60 fps line, so this is worth fixing before anything else.

How many fps do the Core i5-12400F and GeForce GTX 1070 get at 1080p (1920 x 1080)?

Around 41 fps on the High preset. The Core i5-12400F tops out near 136 fps and the GeForce GTX 1070 near 41 fps, and the lower of the two sets the frame rate.

The same pair at every resolution

A processor pushes roughly the same number of frames whatever the resolution. A graphics card pushes far fewer as pixels go up. That is why the limit moves as you climb this table, and why a bottleneck figure quoted without a resolution means nothing.

Resolution	Estimated fps	Limited by	Gap
720p (1280 x 720)	56 fps	GPU	16.4%
1080p (1920 x 1080)	41 fps	GPU	38.9%
1440p (2560 x 1440)	30 fps	GPU	55%
Ultrawide 1440p (3440 x 1440)	20 fps	GPU	70.4%
4K (3840 x 2160)	12 fps	GPU	82.8%
8K (7680 x 4320)	5 fps	GPU	93.2%

What to do about it

The GeForce RTX 5060 is the slowest card that puts this build back in balance at 1080p (1920 x 1080). Your Core i5-12400F has the headroom to drive it, so the card is where the money should go.
