Need help building a new PC...

Greetings to all. I find myself at a bit of a crossroads regarding a new computer build; I have actually already put together a potential configuration through Micro Center, so I am attaching the link here for your review. I would be most grateful if you could offer your expert commentary on whether anything seems amiss, and perhaps provide some guidance regarding the graphics card—I am currently weighing my options between this one and an NVIDIA GeForce GTX series. Furthermore, I wonder if it might be possible to secure these components at a more economical price point than what is listed below? Where might I look to trim the budget without sacrificing quality? I am also curious about the processor; is its performance sufficient for my needs, and will I require a more robust power supply to support the entire system? My total budget sits at approximately $1833...
P.S. As I am a newcomer to this forum, please do let me know if I have mistakenly posted this in the wrong section! Much appreciated
