I've been wanting to build a PC for a while, and about 6 months ago I started on this one. I purchased the parts in the Netherlands, so it's a bit more expensive. I was unsure about the parts for quite a while before I pulled the trigger and started to purchase. I'm very happy with the result. I wanted the build to be very silent, and right now the only parts that really makes noise is the HDD.
I've tried a bit of overclocking, but I ended up using the automatic overclocking tool on my Gigabyte motherboard, which worked really well, and when I started to go any higher it would become unstable. For the gpu I just looked at the results other people got and went a little lower then that. I couldn't find the monitor on here, but this one is very close to the one I have, except that mine is 75hz.
I mostly play GTA 5 and Battlefield 1. I can play GTA 5 almost maxed out around 55-65fps, and I play Battlefield 1 on ultra with around 90fps, which is really smooth on 75hz. Freesync is really awesome, since you don't notice dips so you can set the settings higher.
In the future I plan on building a custom desk, and fully switching to SSD storage. I would also be interested in an nvme SSD, but those are a bit expensive. I also plan on getting a better looking cable to my GPU, because right now it looks quite ugly.
