Is the STGAubron Intel i7 Gaming Desktop Worth It?

I recently bought the STGAubron Intel i7 Gaming Desktop and was pretty excited about its specs. After setting it up, I noticed some lag when running newer games at high settings, which was surprising given the advertised performance. I’ve heard good things about the value, but now I’m wondering if I should have gone for a different build.

Interesting:

Has anyone here used this desktop for gaming? Does it really deliver the performance and value it’s supposed to? Or am I better off upgrading some components or returning it? Would love some real-world experiences before I decide what to do next.
