First ever gaming PC

(Ignore the dusts) Originally, I bought this prebuild back at the beginning of 2020 right before the covid hit. I was planning to build one myself, but this prebuild was too good to pass which I only paid for $1100. This build has a Ryzen 3700x, RTX 2070 Super, 16g ram, 240g SSD, 1TB HDD, and some sort of Master Cooler 120 AIO. However, I did some “mods” since it was not perfect, such as, the case and the power supply. I use this PC mainly for AAA titles, and some competitive e-sport as well. I am planning to get myself a 3070 in the future, but I am not sure how much my 3700x will bottleneck it. If anyone knows, please tell me because I am really not planning to upgrade the CPU, if I were, I would have to upgrade the motherboard since is a mediocre one.
