Bought a G535: what to test/stress test before return period is over

As title says I recently bought a PowerSpec G535 with a Gigabyte RX 9070 XT, and I’m trying to thoroughly test everything before my return period is over. (9/20)

I’ve been reading some concerning reports about Gigabyte’s 9070 XT cards and wanted to see if anyone here has personally experienced any serious issues with theirs.

In particular, I’ve seen reports about excessive thermal paste on some GPUs, apparently including cards with serial numbers starting with SN25. Or the PC crashing once you turn on expo for the ram.

I’m planning on stress testing the GPU, CPU, RAM, storage, etc., but I’d really appreciate hearing from anyone who owns this specific GPU or has experience with the G535.

Are there any particular tests, temperatures, problems, or things I should be looking out for before the return window closes?
