i9 9900k to 7800x3d?

[kernow34]

Hi...ive got an i9 9900k OC to 5.0ghz on all cores. Ive recently bought a RTX 4080 and us a 34inch 1440p ultrawide 144hz monitor. I've been told that my GPU is probably bottlenecking?

Full current system is I9 9900k, 32gb DDR4 @ 3600, RTX 4080 and a 1000w psu.

System i'm looking at is A 7800X3D, Asus Strix X670e-a gaming board....either 32gb/64GB{just to fill all 4 slots) Corsair Vengence 6000 c30.

All the parts I need are currently in stock at last....I just kinda of wondered if ill see much of a performence increase?...i've googled ect but theres not much comaparison between these chips that I can see, and haven't really been keeping up to date
over the last few years. I mainly game, do a lot of VR and have multiple devices running off my PC.

Is it worth the upgrade?....or should i wait for next gen?....Thanks for any advice.

I think a 9900K is long past its best days as a high end gaming CPU.

If we assume the 10700K is equivalent then even at 1440P the 7800X3D is some 53% faster. This with a 4090 but a 4080 is not far behind...

Thank you ....thats helped a lot.. looks like its def worth it in that case. I'll get it ordered....not had an AMD system for about 15 years, fingers crossed I get no issues. Thank again.

I've run a Ryzen 5800X for more than 2 years. Its been flawless, rock solid.

Make sure you update the bios on the motherboard straight away , ther has been burning issues with the 7000x3d.

Or get something that isn't from Asus. Sorry Asus fans but Asus motherboards have been nothing but problematic of late.

Is there any reason you're wanting a £600 Motherboard? I'm wondering if you would do just as well with something a bit cheaper?

It's not just Asus motherboards but agree I'm not a fan also , would take MSI or Gigabyte over Asus and apparently there customer services are poor.

Some friends of mine on our Discord have just built the same system some with 4090's though... and seem quite happy with the Asus boards...other than one guy who has managed to bend the pins and has had to buy another ....

It's mainly an Icue thing for me as ive bought a lot of Corsair fans, my card is ARGB so from what I understand the Asus boards are Icue compatible...the board i'm currently looking at is the www.overclockers.co.uk/asus-rog-strix-x670e-a-gaming-wifi-socket-am5-ddr5-atx-motherboard-mb-6j7-as.html

It's about £380 which is more than what i'd want to pay....but with the other guys on Discord ive got something to get feedback/support/compare with if I get any issues.

You're not upgrading just because you've been told that, right? If you're happy with it, then I wouldn't bother.

Well... thats kinda of what I was asking to see if it was worth it, my I9 is solid enough but i'd like to get the most out of my card and future proof a bit,and i'm curreently in a position where I can...if was just a few FPS then I wouldn't bother... but the above graph from humbug suggests I would get a lot more

I made that exact move (9900k to 7800x3d) and I also use a 1440p ultrawide (though I have a 3090 not a 4090)! Realistically it will depend what you play - I saw maybe a 30-50fps increase in BF2042 (it was already fine tbh...), but things like Tarkov where it's heavily CPU-bound is where it shines. On the latest map I literally doubled fps.

The 'burn' issue is not exclusive to ASUS, it affects all motherboard manufacturers.

There's a few things to keep in mind from the TPU article:

- They're using a resolution of 2560 x 1440, but you have an ultrawide, which depending on the resolution can be closer to 4K than 1440p.
- The type of games you're playing and the settings you're using can have a big impact on where the bottleneck is.
- The FPS gain when the CPU is the bottleneck is often not significant from a playability perspective, unless the lows start dipping under 60 fps (depends on how you experience games though, some people are less sensitive than others).
- You can often force the bottleneck back to the GPU by playing newer games and using higher settings.

I'm not saying don't upgrade, just to take the advice in context for your situation.

I moved from a 8700K to a 12600K and it was worth as I've noticed the gains, the upgrade cost about £50 after selling the 8700K system and I got to keep my DDR4. I've recently moved to a 13600K as the upgrade cost about £35 after selling the 12600K.

Part of the reason why I upgraded was because I wanted to give my 8700K system abit longer life by going to a 9900K but the prices for them was stupid as I got my 12600K just under £200 about a year ago while a 9900K where going for £250+
I've checked today and the prices for the 9900K have come down a little but people still paying over the odds for them which is great if one wants to sell.

Oh I also noticed that the 12600K can use a a lot less power in a lot of workloads compared to the 8700K so a 7800X3D will be even better compared to a 9900K.

Thank you for the advice I play at 3440 x 1440,currently playing mainly fps games, warzone, BF, Farcry's and some star citezen ect....my system isn't eactly struggling... just wasn't sure how much performence i'm losing from the card if bottlenecked....Thanks for taking the time and explaining it a little further... Ive ordered the bits now anyway, fingers crossed it all goes smoothly.

You'll see a small bump in games but it won't be that noticeable
You'll see a bigger gain if you're using your PC for other things

I went from a 9900k to a 13900k
Gaming is similar. Frame rates are higher, but in games it effects they were pretty high anyway so from a gameplay standpoint it's not too different
I also use my PC for encoding though and this is where I noticed the most difference. It's a lot quicker, the upgrade is huge.

So yea, kinda pointless for just gaming. You'll notice the frame rate counter has a higher number, but with that disabled, outside of one or two games you'll be hard pressed to tell the difference

 

[jigger]

You’ll see a massive jump in gaming performance, that’s for sure. The 7800X3D can tap out the highest end graphics cards.

 

[Woodsta888]

X3D chips are gamers heaven. Not so much to do with the average FPS but what the X3D's do for 1% lows, meaning smoother fps - not to be under estimated. These are almost discreet gaming CPU's - INtel need to take note.

 

[Gazanimal]

I'm doing the exact same jump, not that I'm particularly unhappy with my i9 9900K or anything, but I want to upgrade my wife's PC so what better excuse than to upgrade mine and let her have my i9
I'm not expecting massive leaps, only in some CPU intensive tasks/games, but it'll help.
Your new system is going to be the same as mine. Hopefully everything will be arriving tomorrow at some point, although I already have the CPU and boot drive.

 

[kasbah]

I just did the jump from 9900k to 7950x3d. Pretty significant upgrade in some games. I play a lot of Tarkov and I get 120 fps now on most maps up from 70ish.
