Going from a 5800x and 6900xt TO 7800x3d and 4090.. on a 120Hz Monitor. Good idea?

Hi,
Just a quick question. I'm thinking of upgrading from a 5800x and a 6900xt to a 7800x3d and a 4090. I have a 34" ultrawide 3440x1440 at 120Hz. I don't plan to upgrade for at least another 3-4 years. I know 120fps would be my limit with my monitor, would a 4090 be overkill? Or would this be a worthy upgrade, given how long my next one would be?
Thanks for any help or suggestions.

Probably.

What fps are you reaching with your current setup??

Depends on the game, but averages 90-110ish. I'd like to max out the settings and get a constant 120. Also I'd have to upgrade my 850watt PSU to 1000, if I got the 4090. So I was thinking of doing a whole system upgrade to keep me going.
 
It’s going to pump out something like 230fps in games with that res at ultra settings. You’d happily reach 120fps with a 4070 at ultra. 4070ti is going to average 160, 4080 - 200fps. From what I can see the 4070ti is sweet spot for 1440p and ultra wide (I have the same res). 4080 and 4090 I’m sure are lovely but ludicrously overpriced for what they are. They’re really designed to pump for 4k res and make that res playable at around 60fps minimum. Even then, they are way way overpriced.

Thanks for the suggestion. It got me looking at some benchmarks, because I never considered the 4070ti. It has about a 10-20fps increase over my 6900xt, and for £800-£900, that isn't worth it to me. I know my monitor is restricting me at 120fps so I understand your point, but ideally a bigger upgrade would future-proof me until I can eventually get a new monitor.

I wouldn't transition from a 6900XT to a 4070, I'd feel shafted even if I was desperate let alone if I already had a damn good GPU.

In fact a 4070 is often going to be slower than a 6900XT, it's on par with a 6800 and slower than a 6800XT in some situations:

GeForce RTX 4070 (founder edition) review

The GeForce RTX 4070 (12GB) is released today, we have planned multiple reviews including our founder edition card. targeted at ray tracing, DLSS, and AI-powered assists, the GeForce RTX 4070 offers q... Assassins Creed: Valhalla
www.guru3d.com www.guru3d.com

Unless the OP can get a damned good deal and sell their current card for a good amount it's not worth aiming for anything at the moment, forget about "ultra" settings and just turn some stuff down in order to maintain your desired framerates. There's usually little to no real visual benefit from maxing a game out over high settings anyway, you're peeing money down the drain otherwise tbh.

Terrible idea and a total waste of money.

£450 cpu
£250 mobo
£200 psu
£150 ddr5
£1800 gpu

Close to £3000 for 10 extra fps, and even the best eyes wont tell the difference between 110 and 120 fps.

I'd be looking to see how your cpu is currently holding up in the games you play, same goes for the gpu in all honesty.

I'm not sure I'd buy a gen1 am5, seen far too many 'issues' popping up including x3d chips 'overheating'.... Seeing as you have an 850w psu (I assume good quality) you could maybe consider a 4080 and a 5800x3d (second hand maybe) although you could argue both are rather overpriced, they'd be around £1400 new. Depending on ram, that might be worth an upgrade too... what are you currently running?.

In all honesty though, I'm not sure it's worth the upgrade at the current prices but it really does depend on the games etc you use.

Not sure how urgent the upgrade is but I'd maybe try and hold off until nvidia has their quarterly stuff for shareholders, it might encourage some price decreases but don't hold your breath on it.

And to be honest, at the rate things are going with pc games I'd argue vram is going to be a bigger issue long before gpu performance is especially at higher resolutions, rumours seem to suggest we're likely getting updates to consoles within the next few years and a lot of pc games a poorly optimised ports at the mo.

I would echo the don't bother upgrading folks. I know new and shiny is exciting and you want to max out frames but it's a lot of money for barely any improvement.

Having spent £3000 in another 1-2 years you will be in the same predicament.

I am at same resolution (albeit monitor refresh rate is a lot lower) and one of my most likely upgrade is to a 6950xt.

If you do truly notice the frames, I would switch from ultra to high as your frames get below where you want. FSR3 is also due in the next year which may help.

If it were me I would set aside the lower end of the money you have budgeted put it somewhere that's get some interest and add to it now and then. In another year or two re-evaluate. At the moment £3000 for 10% does not seem good value.
 
I wouldn't spend £3000 for a 10% gain in fps thats stupid. Its not just about reaching my fps limit for my monitor, its also to max out the details and enable raytracing, and I would get this from just a new gfx card. Please correct me if I'm wrong, but if you're getting a constant 120fps on a 120Hz monitor, anymore fps are not noticed by the eye. And besides, my wife suggested an upgrade if I wanted one. So I'm finding it hard to read some of your perfectly sound advice to be honest :)

Well if the wife is 'allowing' you a free pass on an upgrade... I'd be expecting her to be after something in return though :P

This is also going to be very close to a new build, you might need a new case due to the size of the gpu, you've already said about a new psu if you go 4090, new cpu means new motherboard and new ram, you might need a beefier cpu cooler and throw in an nvme drive if you don't have one.... all that's left is literally a new os and any secondary storage.... You could sell your old pc or repurpose it.


As to 120fps/120hz... basically you'd be losing the frames visually but you could possibly gain in the speed at which your mouse etc responds (can't remember the exact term but it's the millisecond measurement)

Its a complete rebuild virtually to go 7800x3d, so it not just a gfx card.

And you would be close to £3000 to do it.

The performance jump between the two systems will be substantial. After playing around with a 7800X3D I was shocked by just how much of a lead the 7800X3D opened up over everything else.

The 7800X3D can definitely tap out a RTX4090 and offers enough performance to run games out of sync from the monitor. If the upgrade is worth the cost of admission is a question only you can answer, but the difference in performance between a 5800X and 7800X3D system is bonkers.
 
Thanks for all the help! I really appreciate it. If I did upgrade, I'd probably do the 4090 first, then the 7800x3d later. I think my PSU would be fine atm (850W Corsair) and my case would be able to fit a 4090. I currently have a 6900xt,5800x,ROG STRIX B550 and 32GB G.Skill 3600 RAM, which I'd sell. That would soften the blow a bit and maybe some of the AM5 boards will come down.

Like we said above, you're basically looking at a new build so it might be better to just bite the bullet and do it all in one go, selling the old pc as a whole at the same time.

Unless you want a nest of extra cables you'll need a 12vhpwr cable for the corsair, which is supposed to support 600w. You might be power limited with the 850w due to lack of spare pcie sockets
 
I had a 4090 on a 5900X. Would not do again. Got a 7800X3D and it's game changing. So unless you're planning to change your CPU shortly after I would do all at once or get a cheaper GPU.

850 W wasn't enough for a 4090 and 5900X. Would definatley go 1000W or above if you do go ahead.
