Is it time for me to get a whole new pc, or is there anything I can salvage from this one?
I'm not very tech savvy so please bear with me.
I bought a premade in 2018 and I've only updated the graphics card and ram since then.
I'm using a 55" Samsung TV as a monitor.
It's really starting to get sluggish/finicky.
Gaming example: it can run BGate3 on medium but starts having issues any higher.
Processor: Intel Core i3-8100 Coffee Lake CPU, 4 Cores, 3.6GHz
It's hooked up to my TV because I use it for everything from simple browsing, YouTube, streaming TV/movies, to gaming.
For games the most taxing is something like BG3, but I can't think of anything else in terms of taxing programmes.
I don't think I'd have a use for it if I kept it.
Even if I kept the hard drive I'd have to research How and What To Save To Which Drive On Your PC, but if that's what y'all recommend then I can.
I'm not against investing a few grand if it's the right money spent at the right time, if that makes sense? My worry about changing individual parts is the standard worries about installation and compatibility, but if it's too soon to be changing the whole rig then I can get over that
As a fellow TV-as-a-monitor enthusiast, it might be your display. Most TVs do a lot of frame processing to give you smoother playback at the cost of latency, making games feel sluggish. My TV has a "Gaming" preset that actually turns off some of that processing, allowing for 60hz refresh rate and minimal latency. Might be worth checking your TV for a setting like that.
I usually leave mine on game mode for day-to-day stuff because the mouse latency is unbearable otherwise. However when watching a movie or TV show, I'll swap it back over to cinema mode to smooth out frames and reduce artifacting.
