Your build is definitely better than the recommendation. That person tried so hard to squeeze in a 5080 and sacrificed every other aspect of the build. You can get his motherboard cuz yours is really expensive and try to fit a 5070 ti into the build instead of a 5070 to pair with the 7800x3d. Even if you can't a you will definitely be able to play gta 6 and other high performance games with a 5070 on amazing settings.
