I decided to do this build as an upgrade for gaming after my first computer, a second hand purchase with an i5-4670 and a 750Ti replaced by a 1060 6Go.
So for this one I picked up every parts one by one, and build it from scratch, learning by watching How to's and Build guides on YT.
The choice of the motherboard is maybe a bit overkill for a non -k CPU, but I was seeing further and already planning an upgrade.
I got the CPU and the GPU for the price of used ones, but they were in sealed boxes and perfect condition, so we can say new.
Apart of that it's pretty straight forward here : the 1080Ti Xtreme edition is still a beast in 2021 for 1080p casual gaming.
After this build I reused the CPU and the case to do my Snow Ball (check my other builds).
Oh and yes : everyone know that more RGB give you more FPS so... RGB ftw. ^^
