Right now, I am looking to upgrade from my old computer here: https://pcpartpicker.com/list/vgVQTH. I'm upgrading from this one because it can take a while for videos to render (we get Adobe CC Premier free) and some games are only running on 1080p low quality at or sub 60fps (Overwatch, Pubg, Prey, Doom,etc). My planned build right now is: https://pcpartpicker.com/list/CzMk4C. What is going on, is this semester I will also need to do CAD, programming, and some computer simulations (I know I will be using at least Unity for "games", I believe) along with the above video rendering for classes and research. I will also try gaming on it, and possibly streaming, at medium-high quality 1080p 60fps. If at all possible, 1080p 144fps, and finally, if it's within budget, 1440p 144fps. I already found a used monitor for 1440p and 144hz but my graphics card can't handle it yet. I may buy a smaller monitor to use for having textbooks open, music playlists or,if I do it, viewing stream comments. Finally, my budget is US$800, but if I could bring it closer to US$700 or even US$600 and still be able to do the rendering and gaming, that would be amazing. I know already that I could wait to see if the RX 580 4/8Gb drops back to $200/$230 MSRP, the 1060 6Gb at $260 or get the CPU,GPU and RAM used for much cheaper overall. Some components may be overkill so any help narrowing down the needed specs and overall cost would be fantastic and appreciated!
