This was a big shift from my previous machine. As a game developer and 3D artist, I started working on bigger and bigger projects, until my previous PC was not nearly enough to handle the rendering and high memory usage.
I wanted a build that would be able to handle very large projects, and keep minimum rendering time, for at least 7 or 8 years. Since money is not really a problem for me, I decided to go with an intel i9 and a GeForce 2080.
Going from my previous intel i7 and 920 Mx, with my modest 8Gb memory, the change felt phenomenal at first (I got used to it quickly, now it's going back to my previous machine that feels slow). I tried re-rendering a few animation projects just to see the difference, and effectively went from 6 hours to a mere hour and a half. It's probably a bit overkill, but since my goal is to keep this PC for the next decade, this will probably quickly become average.
The only small issue I encountered was during Windows installation, when I had a hard time making it recognize my mouse and keyboard. After three different keyboards, and a dozen USB port switching, I got it to work, and was able to go through the installation seamlessly.
