New PC

I built my old PC system way back in July 2009 and it's slowly been getting a bit long in the tooth; it still played games fairly well, mainly thanks to the fact that I had upgraded the memory and gfx card along the way. However, earlier this year I thought it was high time to upgrade and build myself a new PC. I started building mid-July 2019 and it has the following components in it:

Aerocool Aero-500-RGB-WH ATX Mid Tower Case
Corsair TXM Gold 650W 80+ Gold PSU
5x Arctic F12 74 CFM 120 mm Case Fans

AMD Ryzen 3 1200 CPU
Gigabyte X470 AORUS ULTRA GAMING Motherboard
16 GB (2 x 8 GB) Kingston HyperX Predator DDR4-3200 Memory

Gigabyte Radeon RX 570 4 GB AORUS Video Card

Gigabyte 256 GB M.2-2280 NVME Solid State Boot Drive
ADATA SU800 2 TB 2.5" Solid State Games Drive
Patriot Blast 960 GB 2.5" Solid State Storage Drive

Even with the upgraded GFX card (an R9 380X) my old PC only ever really managed medium settings at best in most modern games. So far, everything I've tried on the new PC, I have managed to run at High/Very High/Ultra as appropriate in each game with no noticeable slow-down; although, I did have to use a 60fps limit in Guild Wars 2.
