What are system requirements for developing a AAA title on Unreal Engine 4?

Hi everyone…
Question related to hardware…
These are 8 options which suits my budget, from which i intend to take one, but very much confused.

1 HP Z2 Mini G4

2 HP Z2 SSF G4

3 HP Z2 Tower G4

4 HP EliteDesk 800 G4 Tower PC

5 HP EliteDesk 800 G4 Desktop Mini Business PC

6 HP ProDesk 400 G5 MT

7 HP PAVILION GAMING DESKTOP 790-0050XT

8 HP ENVY DESKTOP – 795- 0030QD

The type of project i want to develop is like very much AAA title. And also I am an indie game developer so all the applications like ( blender, unity, adobe, 3dsmax) will be run on it.

Regards

P.S
All the options are with i5 or i7 8th gen, with 16gb ram and 340 SSD.

very much AAA title. And also I am an indie game developer

thats contradictory. AAA pretty much just means you have millions of dollars and a large team to throw at a project. indie is usually small team with limited resources.

in response to your question i would say any cpu i5 or better would be fine and get a decent gpu. of course the more performance the better and the more memory the better too (i have 32 GB and havent had a issue). the thing with performance is it lets you get things done quicker, once you meet the min spec of what your game / the engine requires thats all more performance does. also if your working solo keep in mind your target audience, they may not have cutting edge PCs so for testing a average pc may be ok.

long story short buy the best you can afford or what your comfortable with spending. you can always upgrade components later. you may also think about building your own pc as it will give you better bang for your buck and wont have bloatware.

are with i5 or i7 8th gen, with 16gb ram and 340 SSD

a last note on this part, the CPUs should be fine and the memory should be ok to get you started, i would go for more harddrive space though. assuming 340 ssd means a 340GB which is somewhat small if its the only drive. though given that these are all prebuilt theres probably also a mechanical drive in there too so you may be fine.
