Not really. They're all the same. The build quality is usually good in that it's assembled properly with the components you requested, but if you need any kind of support it's a pain. They lower their margins to compete with the big brands, and support is where they skimp. They can take the hit of some negative reviews because most systems don't have those issues. And because they do the majority of their business prefab on Amazon and NewEgg now, most of their returns are processed by others, replacements arrive quickly, and most reviews end up being positive. It's all the law of averages for them now, unfortunately. And the same is generally true for the other semi-reputable PC building companies.
So you can send it back and wait for a refund if you think the replacement component won't get to you faster. If you do that, just choose a prefab config on Amazon to reduce headaches. And if you wait for the GPU and that was the problem, the system will likely then survive the warranty window and you'll most likely be good to go. The up side with those companies is that they do use the quality, name brand components you select, so you can typically trust that they'll be just as reliable as they would be purchased from anywhere else. You just got unlucky.
I bought two systems direct from CyberPower in the mid-aughts. One was fine but the other had a power supply go up. Same exact issue you're dealing with now -- terrible communication that took days to get anything going and then zero faith that anything was actually going to happen because of how shitty they were to deal with. Because it was an $80 part and I knew the exact model, I just ordered another one, swapped it out, waited for CyberPower's replacement and returned that one. They shipped the replacement via slug, so it took them like 2 weeks. I felt bad pulling a fast one on NewEgg, but I suppose there was ultimately no real harm and I needed that issue solved.
Not sure you want to do that with GPUs still pricey and the diagnosis being iffy, but it's an option. Otherwise, the big brands are a bit easier to deal with (outsourced support that can be troublesome, but 24/7 access and solid return/shipping policies, sometimes warranty deals via Best Buy, etc.). The days of egregious bloatware are mostly over and easily remedied regardless, and their prices can be decent. Dell still has their
Outlet for returned and refurbished systems with discounts and full warranties that often add up to being really good deals..
