Toying with the idea of doing this upgrade. Computer mostly used for gaming @ 1440p/144hz with 1080Ti (possibly 2080 Super or 2080Ti end of year/beginning of next year).

Worth it? i9-9900 is $400 @ MC and I figure I can get maybe $75-$100 for i5-8400.

What do you guys think?
 
Not worth it until you get the 2080 ti. Unless you're like me and do settings more toward 144 fps rather than all max settings.
 
Depends on what games.
I play shooters, lowest quality possible, framerate is everything.
1080ti is fine.

I also play BRs, so when you get in a large player count situation and a lot is going on watch a 2080ti choke down to 140-ish frames.

Add large player count, poorly optimized graphics, crank to medium otherwise you get vertigo from poor graphics in a game update, and you get this:

Granted I'm trying to sell my 1700x, my 2600 would net better framerate. But there are people with 900ks & 2080tis struggling on this mode. Same thing happened with MW ground war. All the 200+ fps guys were down to 140-ish.....about the same as me on a 2600 and 1080ti.
 
You may see a little bit more differences with dual RTX 2080TI 4K but if you look for real differences in gaming, what you need if is a better graphics card. 2600 or 8400 are good enough for one middle range graphics cards.
 
Depends on the game.

While recording at HQ shadowplay:

MW beta was cranking 160fps - 140 FPS depending on what side of the map I was looking at.
BO4 degraded steadily from 160fps at launch to 130fps now.

This was using a 2600 @ 4.1ghz with a 1080ti on an XB271hu.
Something around an 8400 would be similar, add 10fps if you aren’t recording.

Do your games scale to 8 cores?
Do they have an affinity for hyperthreading off?
Is +1ghz going to dramatically change your 1% lows?

Do you plan on upgrading to fiber and stream a lot anytime soon?

I think right now any 2018+ $100 midrange 6 core + 1080ti is the sweetspot if you are gaming and maybe recording.


Should a 9400f keep pace with an 8700k within margin of error if software scales beyond 6 core?
Bc a good cross sample of games do not scale past 6 cores in any meaningfully performant manner.
