With black friday right around the corner I was hopeing to get some feedback on what I should be buying to upgrade my PC.

I will reuse my case, 600w power supply, i have 2x 1tb hdd (they are slow 5400 i think) and a valid windows 7/10 license.

That being said what should I get as far as an SSD, motherboard, gpu and cpu? I use my pc for gaming (ffxiv, counter strike, assassins creed, civ 5, pretty much everything) and will often stream netflix or youtube on my second monitor at the same time. I have a budget of a $1000 but would go higher if it would make a significant difference.

Any help is much appreciated
Thanks
