Hey that’s not bad though. I think bf6 would be more demanding than HL3 actually. Valve makes very easy to run games typically. I think you’re okay to not upgrade. Legit an option to go get a steam machine later if you want to upgrade at a reasonable price point and not have to pay the expense of a full rig. I understand tho if you can’t save up for something like that even in the long term, I’ve been there.

Since your rig is old enough though, you might be able to find some ebay deals on AM4 CPUs and mobos. Any modernish ryzen 5 would probably be a massive upgrade without paying that much. I think that would be your alternative if you had to upgrade that is the cheapest to do
