Well then I just made a thread that's been a waste of everyone's time. Great. Just f*cking great. Four pages of nonsensical trivialities.
I think we're just trying to tell you that the upgrade is pointless. There's no need for you to buy new stuff if you're gonna get 10FPS boost in games and slightly better graphics for the price of 700 bucks.
Just stick with the build you use. Once games start to be unplayable then get a new one. Right now, there's no need to. (And forget about games like Dying Light and AC: Unity, its not the PCs fault for not being able to run them, its the developers fault to make them run normally on PCs)
