A:Answer System Integrates, of this scale, pretty much use what they have available. You might have 100 computers built with a Gigabyte GPU, and another 500 with an MSI GPU. This applies to every aspect of the build (with the exception of the CPU). From my understanding, the mobo is at least a Z390. However, they are all consumer-grade (with the possible exception to the PSU, which are usually production/private grade). So once you buy the system -- you can see what parts your computer was built with and then build further upon that.
My biggest upgrade will probably be a different CPU cooler, and maybe another SSD/NVMe m.2.
For this particular build -- the all stars are the i7-9700f (locked, no integrated graphics), and the RTX 2070 Super. Those two items alone put this system at $800-900. With the $1199 sale -- that's simply an amazing deal. I've NEVER bought a pre-built system...but I couldn't pass this one up.
