There is great deal being made about the choice of processor. I dont get that. As has been pointed out this is the ultimate AMD gaming build. The 3950 is the ultimate "gaming" processor, so you have to start with that. Everything else in the build should be geared towards saving money while compromising as little performance as possible. 1tb is just fine for a gaming machine. If you ned 2 to 3tb for your games then you are not a normal user, please dont argue that. FPS review smartly opted for the 2080super, an overpriced card but not as wildly overpriced as the insanely overpriced 2080ti. A card that only gives moderate improvements in games at 4k that not only make it's price ludacris but make it kind of a dodo, if you were building today.The only criticisms I have for the build is the ridiculous case(it is so ugly and it has zero track record) and the fact that the second video card option could have been a 5700xt.
It's the AMD Enthusiast Gaming PC Build, not the AMD Enthusiast Rendering PC Build, and not even just the AMD Enthusiast PC Build. Gaming is the stated mission.
Spending $400 more on 3950x does nothing for Gaming, spending $400 more on 2080 Ti does.
So spending the same amount, and doing better at the stated mission (Gaming), by downgrading the CPU and upgrading the GPU, makes perfect sense.
