Making sure everything should be running as it should.

[DEL 707]

I recently had some computer trouble and needed to replace both my PSU and GPU.
I've done a clean install and everything looks good, but maybe I'm being paranoid and looking for problems, but I've noticed a few micro stutters in some games.
Everything is definitely running faster and smoother, but in Elden Ring and Darktide, I've seen some micro stutters. Nothing game breaking, but it's caught my attention, especially in Darktide.

So I'm wondering what kind of test I can run to make sure my machine is running as fast as it should.

These are my specs -

MSI MAG B550 Tomahawk
AMD Ryzen 7 5800X
Teamgroup DD4-3200 16gb
Sapphire Radeon 6700XT Pulse
WD Blue SN550 2TB NVME M.2 2280 PCIe Gen3 SSD
MSI MPG A850G PSU

I do have the CPU undervolted and XMP enabled on the RAM.
I have not tried any games with default BIOS settings.

I've run Cinebench, twice. Once with undervolting and again with BIOS deafults, with XMP on.

Undervolted

Default Settings

No difference in performance, just cooler running. Both achieving the scores they should be getting.

I've tried to run the GPU stress test in Cinebench, but the program seems to crash at random points.

What's the best program to use to stress test and compare my GPU? I would also like to do the same to my SSD.

I appoligise if I've posted this in the wrong sub forum.
I'm sure it's just me being paranoid after all the bad luck I've had, but a 2nd opinion would help put my mind at ease.

Thanks for the help and reassurance.

Darktide is the worse offender, but that ran like crap before my PC blew up.
