I like to use Prime 95 26.6 non avx for cpu stability/thermal testing.
I also use aida 64 for additional memory and cpu testing.
For GPU benchmarking, I use a unigine heaven/valley/superposition (dependibg on hardware specs) and msi afterburner for temp checking/overclocking.
I do basically the same as remix but I run Realbench as well.
Except I also use FF XV Benchmark running in a loop for GPU OC testing and overall system stability.
And I use Memtest86+ and TPU's Memtest64 to verify RAM OC stability.
I start with CPU-Z as it's a simple one to start with. I then move to Cinebench, Prime 95, and then two specific game titles Ashes and Wildlands. I have had several configurations pass all but the games.
