I want to upgrading my current GTX 1070 to a 3070 and im currently running a I7 10700K cpu. I've read online there will be 11% bottleneck and that the CPU isnt enough.
I dont know much about these things so im asking here for advice. Would this be a suitable upgrade?
Im upgrading because i have the extra cash. I play mostly on high settings 1080p and then csgo on 1280x960 all 240hz.

My current specs are:
CPU: Intel Quad Core i7-10700k
CPU Cooler: Cooler Master MA410M
GPU: GTX 1070 8GB
Motherboard: Asus Prime Z490-A
RAM: Kingston Ballstix RGB 2x8gb 3200mhz
SSD: Samsung 970 EVO 500GB + Kingston HyperX 3K SSD 120GB
Hard Drive: Stagate Barracuda 1TB 7200rpm
PSU: Antec 750w

Bottlenecking depends heavily on settings used.
In low resolution, high fps mode you'll always be cpu bottlenecked.
With ultra high resolution almost always - gpu bottlenecked.
It's up to you to find appropriate balance of resolution/graphics quality settings for your specific hardware.

If you're playing only on 1080p (no 1440p, no 4k), then you probably don't need 3070.
Only if for additional RTX/Raytracing/DLSS features.

I'll be honest, got rtx 3070 recently and under loads or even first second of furmark all I got was crashes, so definitely looking into your power supply, I was running 1060 which at best draws 120 watt while 3070 does 270 watt or even more at power spikes and power supply goes insane with it and pc just shutdowns. So definitely sad buy for now for me. Trying to fix.
 
First off: Any "bottleneck calculator" can only guess.

It really depends on the games you're playing and the settings you're using.
I guess in CS:GO on 1280x960 the 10700K was limiting the 1070 already.

As little anecdote: I'm running a 3570K paired with a GTX 1060 for a while now and in some games it's the CPU and in some the GPU that limits. And where the limit occurs wildly differs between games.
  • In Stalker SoC I'm pegged on one core but at around 150-200 FPS, some might say ~30% CPU isn't a "bottleneck", but in this case it absolutely is.
  • in Planetside 2 I'm at constantly >96% CPU and the GPU starts clocking down due to lack of utilization
  • in Fallout 4 I'm pretty much GPU limited all the time, but especially in big settlements with lots of assets and barely dip below 60 fps
  • in Destiny 2 I'm also GPU limited

So it really, really, REALLY, depends on the game.
The higher the settings and resolution and the more "complex" the graphics, the more likely you're GPU limited.
In less graphically demanding games you're more likely CPU limited, but in most cases that happens at well playable framerates.
And if you feel like your CPU is "bottlenecking you", you can use that unused performance of the GPU to increase settings.
