Been saving up for quite some time to build my first gaming & workstation pc (the switch from console to pc is definitely a huge jump and worth it). Picked up an ASUS ROG STRIX RTX2080 O8G initially, but I have stumbled upon this MSI RTX2080Ti Lightning (Non Z) on Newegg the other day so I replaced it with the 2080Ti (I am planning to sell the 2080 on Ebay but I am waiting for the limit increase...)
I built it before the Ryzen 3700X and 3900X was announced, should have waited a bit longer but I am fine with my I9-9900k overclocked to 5.1 GHz at 1.33V. The Non-Z Lightning card is overclocked to almost in par with the Z card (2010 MHz Max, 1950 stable at all temps).
Intel 760p as my boot drive and startup/essential applications, wd black for games, the two Samsung 860 evo on Raid 1 for work.
The Corsair HX1000i is definitely an overkill (total power draw from the system was recorded digitally at 410W which I know isn't accurate but it's a number for reference nonetheless).
The one downside of the entire build is the case, but I love the minimalistic look of the carbide 275r black tempered glass edition, even if I have to cram everything inside and having trouble closing the side panel with all that cables Lol. It's still worth it though!
Hope this build could last a while (5 years at least) without any upgrades.
