After much deliberation, I ordered the 4090 FE and an i9 13900k. The amount of deliberation meant that I missed the delivery window for today so it has to be delivered to work tomorrow! banghead

I built my system with the idea to upgrade to next-gen when available. I have a Corsair 5000D Airflow Case, H150i AIO etc. I didn’t expect the cost to be quite so high! So the rationale and man maths of ‘In for a penny in for a pound’ came into play’ biggrin

I need a new cpu new motherboard new psu and not sure if the 4090 will fit in my current case....not sure if to update my current system or just sell it with the 3080 included and start again.

The lure of new tech...

Depending on your cpu there is not always a lot of performance increase in upgrading

my old 10900k performs well with a 4090, and zero reason to upgrade a 12900k

Depends on the resolution you play at. At 4K an older CPU will provide as many frames as the 4090 can generate. At 1080p the GPU generates frames faster than the CPU can send so you end up bottlenecked with poor GPU utilisation and possibly stuttering.

It's been said before though that if you're playing at anything less than 4k then the 4090 is utterly pointless, even the 4080 will be heavily bottlenecked by pretty much any CPU at lower resolutions.

I'd there isn't any point in frame rates higher than 240 either as you don't benefit ic you watch the reviews of the 500hz monitor that's just come out

I dont get why anyone would drop 2k on a GPU and then run it on a £150 monitor??

i see almost no benefit over 120mhz, my monitor supports 120, 144 and 175, cant see any difference, i leave it on 144

That's not true across the board though. A graphically demanding game will still be GPU limited even at lower resolutions. Cyberpunk, Witcher 3 and Portal RTX are all GPU bound at 1440p.

As time goes on, new games come out, and new gen CPUs emerge, it will balance out more. The 4090 is, arguably, ahead of its time.

You're not alone, a lot of people say exactly the same thing.

In regard to the 4090, pointless getting one at all if you aren't going to use it with a 4k monitor.

I had an alienware 240hz gsynch native 1080p for gaming a while back and it sure wasn't £150.

Not everyone is searching for the same thing. (I have a 4090 and a 4k LG tv btw, but I used to be all about as high a FPS as possible for the only game I Played for a long period.)

The i9 13900k and 4090 FE arrived yesterday. I decided to install the 4090 on its own to see how it ran without the new CPU, the current CPU is a i5 1200k. I got to play DCS, Doom Eternal and BF2042 briefly last night. All were limited by the GPU on my 120hz LG C2 42

I will take another look this evening, but it looks like the 13900k will be going back unopened. I did think it would be overkill, but didn’t think the 12600k would hold up so well. The refund will likely go on a Meta Quest Pro.

Thoughts on the 4090FE?

Ultimately if you are just gaming, having loads of cores is unnecessary. The i9s do slightly better as they run higher clock speeds (as long as you can keep it cool enough) but they run the same architecture and very few games will make use of more than a handful of cores. Enjoy the 4090 biggrin

How did you determine that the GPU was the limiting factor? I have an i5-12600K and a 3070 FE, gaming in VR (Quest 2) and on 1440p 75Hz, interested to know if one or other of the key components is holding things back.

The limiting factor will more often than not be the graphics card. Your specs are well balanced imo. It's when people take an old rig and put in a monster graphics card that you end up with a CPU bottleneck.

The way to check is to run monitoring software, disable all frame rate limiters, and play a graphically demanding game. If you're not seeing high GPU utllisation then you are CPU limited.

Basically this.

I used the Nvidia performance overlay first. Then downloaded MSI Afterburner to verify the results.

I will be digging deeper into Afterburner later today to see what it shows. I only had a short time with it last night.

Thanks both, will investigate.

@Brainpox yeah I scored the 3070FE on release day and was running it with a 6th gen i7 I think, went for the i5-12600K this time round as I figured it would be a better match. Just curious to see what's what with the games I'm playing, particularly in VR as I sometimes get some tearing or occasional screen blackouts in VR in more demanding games (DCSWorld mainly).
