This is my second and current PC build and the first one where I assembled it all by myself. I had a decent build but I wanted a definitive upgrade that would allow me to have high end components for the upcoming years, which made me change the case, motherboard, cpu, cooling and psu. I only kept the graphics card and the RAM, which I plan to upgrade down the road but don't feel like I really need to now. I love the case, I think it's beautiful, and the Kraken x72 just goes perfectly well along with it.
I was already considering a monitor upgrade so that I could go 144Hz. While at it, a huge dilemma appeared: 4K or Ultrawide? I went with the latter since I was not enjoying my 2-monitor setup anyway. The secondary one was just a stantard and cheap TV mainly for watching streams and such so it was highly expendable. The Ultrawide 1440p 144Hz IPS offer is not huge though (understandably) but I'm very satisfied with my choice: LG 34GK950F. It's a Freesync one but it works perfectly with a Nvidia card and the G-Sync version was capped at 120Hz so that's a nono from me.
The graphics card was a consequence of the monitor: my 1070 Ti could handle the weight for sure but at Ultra, higher than 60fps and 3840x1440? Not really so I just decided to remove my last bottleneck on a already great system specwise. That's why I went for a ZOTAC RTX 2080 Ti AMP and I couldn't be happier.
