Built this computer 3 years ago and haven't really added much since then.
CPU - Ryzen 5 1600 - Takes anything I throw at it and almost never goes above 70% utilization
MOBO - MSI X370 SLI Plus - It's a Mobo. Nothing really special about it but it hasn't given me ANY problems in the past 3 years
RAM - Corsair Vengeance RGB 16GB - The RAM is alright. It works well for what it's supposed to do but the software is horrible
SSD #1 - Samsung 850 EVO 500GB- This is the original SSD I put in my computer. It is about 4-5 years old at the moment as I was using it in a previous computer. Read/Write speeds are still up there and were benchmarked last night at 548MB/s read, 532MB/s write.
SSD #2 - Samsung 970 Evo Plus 500GB - I just got this SSD a few days ago. Seamless install with my MOBO and amazing read/write speeds. Benchmarked last night at 3.4GB/s read and 2.9GB/s write.
HDD - WD Blue 4TB - Standard HDD. Really nothing to say about it. Benchmarked at 179MB/s both read & write.
GPU - EVGA GeForce GTX 1070 SC 8GB - Amazing graphics card for the money. I bought it when GPU prices were booming so I spent a lot more than MSRP but I can play any game on it that I throw at it at 1080p 100+ FPS. I did have to RMA the card in the first two weeks due to artifacts on the screen but since then, no issues.
Case - Phanteks Eclipse P400S TGE - Great case for the money. Amazing airflow & temps, and a LOT of room for cable management. Having a modular PSU helps too.
PSU - I've had no issues with this PSU in the past 3 years.
Monitor #1 - Asus VP279Q-P 27" - This is the original monitor I ordered when I built this computer. It's lasted me 3 years with no issues with dead pixels.
Monitor #2 - MSI Optix G27C4 27" - I just bought this monitor yesterday and so far it's absolutely amazing. The refresh rates on it are butter smooth and you adapt to the curvature of the monitor very quickly even if you've never played on a curved monitor before.
Keyboard - Razer Ornata Chroma - I love this keyboard. I like a tactile key but I'm not a fan of a lot of key travel as I generally type closer to the keyboard and end up hitting a lot of different keys by mistake with the higher keys. The mecha-membrane doesn't exactly feel like a mechanical keyboard but the tactile-ness of the mecha-membrane switches is amazing.
Mouse - Razer Viper - I just started using this mouse about two weeks ago and so far it's been alright. I generally like bigger mice as I have larger hands and this mouse is a little smaller in the palm area. It's going to take a little bit to get used to.
Headset - Steelseries Arctis 7 - I absolutely love these headphones. The fit on them has gotten a little more uncomfortable over the last 2.5 years but I'm also using the original band so it's lost some of it's tension. My favourite feature of this headset though is the speaker pass-through. My fiancee hates wearing headphones so before I got these, she always changed my sound option to the speakers and I always had to go change them back. With this headset, once the headset shuts off, sound automatically goes through the speakers and once they turn on, sound automatically switches to the headset. I haven't found another headset that has this feature yet.
Speakers - Logitech Z150 - Standard speakers I got from Walmart for $20. Nothing special.
Mousepad - Steelseries QCK Prism - Decent enough mousepad when it's new. I've had it for just about 2.5 years now and the mousepad is starting to wear down. Steelseries however, doesn't sell replacement pads and you actually have to purchase the entire setup all over again. I will not be re-purchasing this product when it comes time for a replacement. I ended up having an old Steelseries Dex that I had to cut to have it fit the QCK Prism and that is working for the time being.
External Drive - Seagate Backup Plus Slim 2TB - Great external drive. It's lasted be 4 years so far and still at full health. Read/Write speeds have not been benchmarked.
