GPU usage worth it?

Greetings!
In the beginning of BOINC SETI I've helped calculating and now finally I'm on it again, this time with Einstein@Home.
My CPU is a Ryzen 9 with 16 cores and my graphics card an RTX2070. The graphics card is really loud so I'm wondering if it's even worth it? My CPU-cooler doesn't really make noise and I can still work on my PC when Einstein uses 90% of my CPU. When I'm not at the PC the GPU can work, too.
So... are there numbers how fast a GPU is compared to a CPU in solving Einstein Calculations? Is it just about FLOPs?
Thanks guys!
/edit: I'm using Einstein when it's cold so my PC can warm up my office. It's really nice that it's warm and the energy is good for something else than just warming up the room :D

Hi Markus, welcome to Einstein!
Your computer details are hidden so we can't see what sort of tasks you may be crunching and what sort of times they are taking.
The simplistic answer is that you're missing out on quite a lot if you can't tolerate GPU crunching on that GPU.
Where is your case located in relation to you? Are you really sure it's the GPU and not perhaps case fans making that much noise?
I'm responding to your message whilst sitting at a long table with 2 screens in the middle and 3 separate stacks (on either side) totaling 11 open cases containing working systems, all around my ear level (or a little higher). There are 11 working GPUs in less than 1.5m of where I'm sitting and there is a relatively soft and gentle hum from all the CPU and GPU fans. The cases are completely open - no case fans, as these tend to annoy me the most. I don't find the hum annoying. There are other more distant sounds that are more noticeable that I'm more conscious of.
Is there nothing you can do in terms of positioning the case that would alleviate the problem? How old is the GPU? Is it running 'dry' (low on lubrication) so that it's creating noise from vibrations?
As an indication of what you are missing out on, I notice that after around a week of joining here, your RAC (from a very decent CPU machine) is listed as around 5K. It will take several weeks to reach its final value and I would guess that might be around 15 - 25K or so for 24/7 operation. If you were using just the GPU on it's own, you could achieve maybe 20-30 times that amount of output - if you were running GRP tasks. There would still be a significant improvement (not as large) if you were running GW tasks.
If you change your privacy preferences to allow people to see the basic hardware and task details for your system, more accurate comments would be possible.
Cheers,
Gary.

Applying some degree of "power limiting" for the GPU could result in lower noise level. And still that GPU would be very productive.

Yes, it's the GPU. My NVIDIA makes a lot of noise, even when it's at 30% and lower temperatures :D
Case fan is controlled and you can't really hear it, CPU fan is a big one and not loud at even 100%.
Thanks! Will have to look into that, because there's no setting for this.

Both my GTX 1060 and my GTX 1650 are very silent. Of course they are not that fast.On the 1650 GPU-Z does not even give me the fan RPM, only says it is mostly 40%. I cannot understand why GW tasks get the same amout of credit (1000) both on a CPU and GPU while GRP tasks on GPU get five times the amount of credit compared to a CPU. But credits are always a mystery in all BOINC projects.

GPU is a lot faster in scientific workloads like E@H. 64x Zen cores are about as fast as a modern GPU, roughly speaking. There is a reason why everyone and their mom is buying GPUs right now.
You can always tweak GPU power consumption and fan speeds yourself. MSI Afterburner for Windows or GreenWithEnvy on Linux do this just fine and easy. 70% TDP makes a lot less noise with only minor decline in performance. You can even do with the new Eco mode (should be visible in Ryzen Master) to reduce TDP (=heat) on your Ryzen, if it is a Zen3 CPU. 5950x can be tweaked down to 65W from 95W for minor performance hit.

My GPU is an RTX 3090 FE. It is extremely loud with fans set at 100%. I just ignore it. It is NO BIG DEAL. You might try ignoring it too. Crunching with a GPU is well worth the minor annoyance you are experiencing.

Is there a chance that there is something wrong with your GPU? How old is it? Did you buy it new or used? Is it under a warranty?

Bought it new last year, but it has always been like that. When the temp is over 50° it starts its engines :) GPU never gets hotter than 60° though. I don't know how to change options here, since it's absolutely no problem for a GPU to be at higher temps
/edit: my GPU usage in Einstein is very low anyway. I donwloaded MSI Afterburner to control my GPU fan. It's quiet now under 60°
Good, glad you've got it

Good, glad you've got it under "control".
Just out of curiosity, what brand is your GPU?

It's an MSI Geforce RTX2070 VENTUS GP 8GB
And I found out that I'm actually stupid. My graphics card makes the same kind of nose like my power supply. I think it might be the power supply I keep hearing at low GPU load...
