What are you wanting to upgrade exactly? Do you want more FPS? Does it struggle with certain tasks like video editing? Are you running out of RAM?
If FPS, what are you trying to achieve?
I get quite a bit of buffering and pauses when playing games and also editing and loading. The FPS is fine when running smooth however on some games there is screen tearing and like i said before with the loading
Hmm, I mean you really shouldn't have any issues. You've got an SSD, 9th gen i5, 16GB of RAM and a 1660 Ti. I could understand if it was having an issue with editing, however, are we sure that it's not just your internet connection causing the buffering?
I mean truly its not terrible so that could be the cause, I just didnt know if there was any slight adjustments to make to help a little bit. I know the one option is upgrading the grahics cards but then it really starts to climb price wise from there.
