Large frame issues often stem from underlying health or lifestyle factors.

Big changes in frame rate from around 160 to about 30 when using Halo Reach. i7490k on a GTX970 with 8GB RAM.
Possible causes include overheating of the CPU or GPU, leading to slowdowns and stuttering. Another issue could be insufficient RAM, which may also result in performance drops. A faulty driver might play a role, though I don't think it's the case here. The PSU and motherboard are likely functioning properly. Overheating in the VRM can restrict power to the CPU, causing slowdowns and stuttering. Is your system receiving adequate cooling?
You’re either running low on memory, your processor is maxed out, or your hard drive is being used intensely causing stutters.
Typically, the CPU that reaches its maximum performance is the one that handles heavy GPU tasks such as textures and AI. Aim for the GPU operating at 99-100% while keeping the CPU below 90-80% or even lower.
Also, do you have a 144Hz display? I tend to reduce a bit in peak FPS for a steadier average frame rate (plus better low-end performance).
The CPU temperature isn't the main issue—it's how much it's being used. Check the task manager ("Ctrl + Shift + Esc") to see its activity. If it hits 100% usage, the game will drop performance significantly. Aim for around 120 FPS instead; push the GPU while letting the CPU relax a bit.
CPU activity stands at half load with 60% utilization of memory.
