From which manufacturer to choose a processor?

Question

Processors

Good afternoon or evening, dear readers!
I wanted to assemble a computer for myself, I already bought an msi geforce rtx 2070 super video card. I ran into a problem that the processor could not load the video card, I thought that everything would work, but I had to buy both the processor and the motherboard.
1. 3 processors in mind:
a) Ryzen 7 3700x (I don’t know which version to take, with or without a boxed cooler, reviews about the cooler vary too much)
b) Intel core i7 9700k or 9700f (Please tell me if the difference between these will be critical two?)
2. I planned to take the motherboard for AMD gigabyte b450 aorus elite, because of its characteristics.
For intel, I don’t really understand motherboards, maybe you can advise something?
I heard that amd processors are very hot and very dependent on RAM, how true is this?
The computer is assembled for games (in priority) and for work in the future, as it turns out.
Thank you all in advance!
PS the choice does not rest on these 3 processors, if there is a better option up to 30k - write.

Answer 1

a) Ryzen 7 3700x

besides the cooler, the difference is that OEM has 1 year warranty, BOX has 3 years. And AMD processors also have delicate thin legs that can bend during the barbaric packaging of OEM processors in traditional adhesive tape.

b) Intel core i7 9700k or 9700f (Please tell me if the difference between these two will be critical?)

processors with F - with a disabled video core, because it is defective. Previously, all processors with a defective video core went into substandard condition, now they add the F index to them and sell them a little cheaper. Do you want to contact rejection?

2. I planned to take the motherboard for AMD gigabyte b450 aorus elite, because of its characteristics

what characteristics?
In general, it makes no sense to contact Intel now - the 9th generation is already outdated, there will be no new processors for socket 1151v2. The new generation on socket 1200 has not yet come out. And what is the point in 2020 of being limited to 8 cores 8 threads in an i7 when for the same price there are 8 cores 16 threads 3700X?
PS Rating 9700K and 3700X in PassMark

Answer 2

And what percentage is worth?
Take intel - because optimization
I love RAM Kingston
Motherboards I have been using for a thousand years from Gigabyte, regardless of whether the percentage is chasing or not - take Z chipset (because the load calculation was for overclocking)
MSI Military is still not bad
I do NOT like asus, asrok not I tried
Cooler - only a tower, for 120 or 140mm ... for example, from inexpensive ZALMAN CNPS10X Optima
or Noctua

Answer 3

Heard amd processors are very hot

It depends on what, ryzens are relatively cold

highly dependent on RAM

It's true. But Intel also depends on it quite strongly. In any case, a good memory is the key to success.
Boxed cooler no no and no again.
In general, both processors will reveal the card to the fullest and even with a large margin, by and large, a matter of personal preferences

Intel core i7 9700k or 9700f (Please tell me if the difference between these two will be critical?)

The only difference is that F-ki does not have built-in video. You don't need it from the word at all
UPD: Comparison of 9700k vs 3700x in games
