From single monitor to triples while being CPU bound?

I'm wondering if anyone has experience with moving to triples while being CPU bound.

Im running a i5 8400 with a 1080ti at 1440p single screen.

During a race, fps fluctuates from 90 - 120 on average. The GPU never goes higher than 50% but individual CPU threads get to around 85% so I guess I'm CPU bound.

Practicing alone on track, I get around 200fps and GPU is around 95%.

My question is, if I move to triples, will my FPS drop to around half during a race as suggested by many websites and forums? Or, because I'm CPU bound, will my FPS remain quite high and I'll notice more of my GPU being utilized?

If anyone else has tried this, I'd appreciate any observations.

Thank you :)

Yes, your fps will drop to about half when going to triples. 1080ti is not really enough for triple 1440p, but it will work well with triple 1080p. GPU is significantly more important with triples than the CPU.

So do you think my GPU usage will stay around 50% with triples? Won't the triple screens make the GPU work harder and I'll be able to use more than the 50% that is being used now? Just wanting to clarify.

No it won't stay at around 50%. Yes the triple screens make the GPU work harder - It will probably go up at around 100%.
Anyway the 1080ti won't be enough for triple 1440p.
 
Thank you all very much.

I've just tried lowering my resolution to 1080p out of curiosity and I got exactly the same framerate in a race (90-120ish).
 
Just an update in case it helps someone in the future.

I tried it with triple 1440p and my GPU went up to 99% as expected.

My framerate dropped by around 20% on average. This is track dependent but overall I'm very happy with the result.
