====================

This is my gaming PC, I bought it one year ago.
I have a gaming channel and it's starting to produce income, so I will be using it for gaming and video editing.
I would like to buy a new Video Card and an extra 8GB of RAM (2x8GB).
Video card that I had in mind was a GTX 1080 or 1070 from ASUS.

Now, I would like you guys to tell me if and how much will this change help me and will I see significant change in the performance of the PC.

Thank you in advance, Levi.

Yes, it will be quite an improvement. You won't need more than the 1070 for 1080p, but if considering jumping to 1440 or 4k, the 1080 would be best. Actually though, if leaning toward eventual 4k, I would wait for the 1080 Ti.

BTW, what OS are you on? If on W7, I would stay on that until W10 is more sorted out for gaming, and Dx12 is used more in development.
