the i9 and also the AMD Ryzen ThreadRipper High End Desktop CPU's are both a waste of space for most but the most utter speed freaks who crave for the highest benchmarks only imo
the i5 and i7 are more than enough for most gamers, or the equivalent AMD chip which for me are the Ryzen 5 which is roughly a i3 to i5 based speed depending on model, as there are 4 cores of 6 core versions then the i7 equivalent which is the Ryzen 7 which is an Eight Core chip
as most games still don't use all cores, or very few, for me a quad or six core is plenty for most.
imo cores aren't as useful and clock speed, so i use a overclocked i7 which is a i7 2700k which runs at 4.2ghz on all 4 cores, plenty good enough to run and test all the game here i need access to, but my gaming rig is a quicker one, again a overclocked model, which was bought overclocked.
imo again, set yourself a budget and see who can get the most out of it, for me, faster clock speed is better than more cores for most, ram either ddr3 or 4, but 16gb either way and a good vga card is the basics, then go for a good SSD with a SSHD for data / storage.
more fans makes for a noisy case, but also a cooler pc, so depending on use, think of good airflow and placement in the room, windows equal extra heat the case will have to get out, so runs the fans more, same as a radiator placed behind it.
if money stretches, go for a fanless case or all water, costs more, but next to no noise.
and my last comment is, my rule of thumb, is build or buy for now and today, as tomorrow something twice as fast will come out and half the price, so don't go for a long term build, sometimes it's better to put in something that's at a good price but not the fastest and replace in a year or so when the faster model has dropped down by half the price etc, once a base is gotten, a pc can be swapped and changed as easy as your O/S
