yeah I confused you with the troll that likes to copy paste the same comment everywhere, I didn't look at the name. sorry. but it isn't my fault that your post was similar in nature
As for your "it can't do it" go check the 9900k review done by techpowerup. it has BF1 at 1080p with a 1080ti.
As for using the 2080ti, trusted reviews are hard to find but Steve did test the 2700x and the 8700k and the averages were 164 vs 183 with the 1% lows being over 100 for both but well below the 144Hz mark. I don't see the point in comparing the 2700x with a 9900k here anyway.
Telling me to go "check" a streamer's FPS counter... really? Those don't update fast enough to show the small dips and I don't know all of his settings. If you want to stream, the 2600x will blow the 9400F out of the water. It's not even close.
But to please you I did check. His BF V video from Dec 17, 2018 shows his FPS counter swing from 170+ to 240+ (270 when looking at the sky) on his 2080ti + 9900k rig (I picked it because of the name used). The video actually starts at under 200 FPS.
The FPS will be lower if you open youtube or twitch while gaming, that is normal. Since we are arguing about extremely small percentages (1-2-3%) it should be taken into account, right? Otherwise what is the point of recommending the 9400F over the 2600X? Every intel fan likes to point out the extra 2-3 FPS but never look at the simple fact that it is up to 50% slower in many other thread intensive tasks.
A gaming PC is not a console, you can and will do other things with it too.
I would also like you to show me any benchmark from a trusted source that shows that big of a difference in performance for the RAM (not a streamer again please) because most tests tell a similar story to what I wrote. You also like to ignore the simple fact that if someone is going to tighten the timings on the 3400MHz RAM then he will do the same on the 3200MHz one so all you are left with is a small bump in speed.
PS: yes I am triggered by people trying to intentionally fool me with fake or intentionally misleading arguments. but beyond confusing the name I only responded with things that can be verified by everybody.
