6GB graphics… what graphics?
32 GB RAM will let you run the editor for smaller projects, but bigger proejcts with heavier assets will probably run out of oomph. Also, if that 6 GB graphics is “built in graphics” of any kind, you’re probably in for a low frame rate.
The i3 versus i5 question is not as important as the “what graphics card is it?” If it’s integrated graphics of any kind (Intel / Iris / Radeon) then it’s unlikely to be suitable for any real-size project.
Also, if this is a laptop, you’re going to want to add a mouse. It’s essentially impossible to be productive in Unreal Editor without a middle mouse button.
