Two things i only think. Ive not had a chance to test this. Intel wins on the high end if you have a graphics card. Amd wins on the low end, because they lower their price of older processors. If you are using integrated graphics intel have not improved since 4000, while amd canabolises ati 100 to 200 dollar graphics cards. Plus the makers of play station processors who use integrated graphics should know integrated graphics. Remember i have not tested this.

I think GalCiv3 will benefit from this upgrade.

Current i5-7600K got much higher frequency, and slightly better performance per core when compared with equal frequency, but still cannot compete in multi-threaded tasks.

Also there are new CoffeLake generation, i5-8600K, i5-8400. These i5 CPUs got two more cores (than i5-7600K) but still miss SMT. So only 6 threads, but may be for many people it will be enough.

On the other hand, there are i7-6800K and i7-7800X, they are comparable with 1600X in most of the tasks and games, but have a much higher price (because of PCI-E lanes, RAM channels, etc.) and requiring expensive motherboards.

If you are playing any sizable galaxies, look to 16 gig min RAM and 32 is better.  Consider SSD to avoid any paging delays.  I am not interested in "good" performance;   I am into really swift response.  If you are looking at CPU responses so hard, do not skimp on RAM.
