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.

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

Thanks will do

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?

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

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.

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.
