@Haikal Prasta if your recording from a capture device, that should be fine (use QuickSync). You should be able to get 1080p30fps or 720p60fps. I have Win10 with OBS streaming and Chrome with 2 tabs and only use 3.7 GB of RAM. Just keep external programs and sources to a minimum. My OBS uses ~470 MB of RAM when completely minimized to system tray. My processor is a year older.
