From this comparison between my ancient i7 and your prospective i3:
i7 vs i3
Im curious to know more about this CPU being a bottleneck issue.
Finally, something I forgot to mention earlier, is that the GPU can always be upgraded in the future way easier than the CPU. Your though of getting a way-less-power 1050 isn’t totally misguided, though it really depends on the kinds of games you want to play and how much you’re willing to sacrifice. I feel as if the 1050 is too much of a compromise, unless all you want to do is play some older games on mid-low settings.
