Recently treated myself to a semi-new build as my current system was being bottlenecked by cheaping out on an i5 rather than i7. Except my current i5 was like 2 generations old now and I couldnt buy a i7 of the matching generation anywhere. So needed a new motherboard, decided to switch up my storage too as I was running a mish-mash of old hard drives and SSDs of varying sizes. Decided to go big or go home, not cheaping out on any components anymore so jumped straight up to the i9 rather than i7. Probably complete overkill but at least I wont have to upgrade again anytime soon.
However the absolute best thing I did was upgrade my monitor from a bog standard 1080p somethingorother, to a 1440p 144Hz G-sync monitor. Cost almost as much as the rest of my PC combined but my god do games look good now running at 140fps and I didnt realise how big a jump in quality it was from 1080p to 1440p.
Also replaced my ageing corsair H1500 headset with a new Steel Series Arctis 7 which are phenomenally good and comfy.
New build:
Asus ROG PG278QE G-Sync monitor
MSI Z490A-Pro motherboard
i9 10900KF CPU
32GB Corsair Vengence RAM
GTX 1080Ti GPU
1 x 250GB Samsung EVO 970 M.2 for boot drive (god damn these are fast, absolutely worth the upgrade, you push the power button and you're already at your desktop)
1 x 2TB Crucial something or other SSD for games library
1 x 2TB mechanical HD for mass slow storage
