it is obviously part of the Low end sector of pc components, it should be able to play games at 1080p medium settings at 60fps in most games. (Without recording)
If you plan to record, you probably need to upgrade that cpu to a kabylake counterpart or wait for coffee lake.
Maybe give that 750ti a lil upgrade ye?
A 1050ti is a pascal option and is a great price to performance option.
If you ain't feeling that money, you can get the GTX 1050, non ti version
that will give you a good performance boost and you could probably record some games in medium settings? Maybe at 50fps idk
