I still have my old-old Dell Optiplex 380 desktop computer. It is now not my primary or even secondary desktop, but it's still here and with an update to Windows 10 it had become unusable. I finally swapped in a Western Digital SSD drive to address that.
The SSD drive upgrade makes Windows usable, which is fine for programs running on the computer. I'm now discovering that video performance is less than stellar. Watching YouTube sites and videos that run fine on the newer computers, I find that on this one the video resolution defaults to lower settings and, even then, the playback is a bit jerky and the audio track gets out of sync with the video track. YouTube videos the auto-run at 720 on my newer Dell desktop only play at 480 on the older box. The video output on the old box is DVI.
So what's the best fix? It's a Dell computer running an Intel Core 2 Duo. The video is integrated, so it's sharing RAM with whatever else is running. It only has 4 GB of RAM.
Option 1 would be to add more RAM. Dunno how much difference that might make.
Option 2 is to install a dedicated video card. It wouldn't be worth going out and buying one, but I have two here that I had bought a while ago but never used. One is an Asus NVidia GEForce 710 with 2 GB of on-board memory. The other is a VisionTek Radeon HD 5450, also with 2 GB of on-board memory. Both have outputs for both DVI and HDMI.
What option is most likely to perk up the video performance?
