Hey there, Liomanoten.
The SSD is a pretty good choice for gaming while recording at the same time. On the other hand, less RAM means running some of the newer games on lower specs.

And if it's a high performance HDD you shouldn't worry about frame drops or stuttering during gaming/recording. Although there's one downside to this - the loading of the games and the in-game loading screens will take more time than if you had an SSD.
