Question Need Suggestion on upgrading R7 5800X3D(good for 2 years) or R7 7800X3D(have to change Ram and Mobo for 7800x3d, old PC parts priced at my location)

[manoj327]

Hi,
I have a old AMD R7 3700x processor cpu and bought a RTX 4090 to perform better in office work (satisfied) and for gaming (unsatisfied). I know my CPU would bottleneck my GPU but i am OK with as long as i get 120FPS in 4k (using DLSS or FSR if not achieved) any game.

Need Suggestion on which one to choose, R7 5800X3D or R7 7800X3D for better game performance keeping cost and 2-years time in mind.

If i get R7 5800X3D:

1. It should serve my purpose of 4k 120FPS (using DLSS or FSR if not achieved)for minimum of 2 years.?
2. Do i have to upgrade ram (present 3200MHZ) to higher MHZ?
3. Star citizen runs well on 5800X3D at 1440p 144HZ and 4k120Hz and what FPS i get compared to R7 7800x3d?

If i get R7 7800X3D:

1. DDR5 Hardware is costly in my location and have to spend 2.5 times more cash to get ram and motherboard compared to 5800x3d, and costs even more to get the Z670 motherboard (pcie 5.0), upgrade worth it?

My PC config:
Processor : R7 3700X
Mobo : Asus Tuf X570
Ram : 32GB DDR 4 3200MHZ corsair
GPU : Zotac RTX 4090 AMP Extreme edition
PSU : Coolermaster MWE 1050W 12VHPWR
Display : 4K TV 120HZ ----------------------------(main)
Display : 2k Monitor 144HZ (1ms)--------------(Secondary)

Thank you for you valuable time

The 5800x3d should be fine and cost a lot less since the video card can't run 120 FPS in all games unless you turn the down.

i am OK with as long as i get 120FPS in 4k any game.

Then, can I take it that this only refers to titles that support DLSS?
'Cause uhh, technology isn't there otherwise.

2. Do i have to upgrade ram (present 3200MHZ) to higher MHZ?
3. Star citizen runs well on 5800X3D at 1440p 144HZ and 4k120Hz and what FPS i get compared to R7 7800x3d?

1)Negative. It lost right out of the gate.
2)No. That cpu wasn't picky about ram because the Vcache filled the role faster ram was supposed to.
3)Star Citizen is still in alpha, isn't it? No telling what CIG may change in a year or 2, and how either chip will be affected by it.

1. DDR5 Hardware is costly in my location and have to spend 2.5 times more cash to get ram and motherboard compared to 5800x3d, and costs even more to get the Z670 motherboard (pcie 5.0), upgrade worth it?

1)IMO, no... but if you got the cash anyway, to heck with my opinion...

Although 3700x is not very powerful gaming at 4k is almost always GPU bound. It does to some extent depend on the game. Things like city simulation game are fairly low res and need more cpu.

What you find though is the cpu is seldom the bottleneck if you are going to run 4k.

I just laugh when you say you want 120fps in any game. Not going to happen. Things like cyperpunk especially with ray tracing on kill even a 4090. You have to use fake frame generation to get even playable rates. The new starfield which does not use raytracing also gets nowhere close to 120fps on a 4090 unless you set the quality down or use their upscaling options.

I have no idea about star citizen but I suspect it too will be limited by the GPU

I mean 4k 120 FPS in all games using DLSS or FSR

Ah. Well, my answers don't change.

So all you care about is FPS. DLSS and any other tricky thing trade the quality of the image for a higher number.
They are all pretend 4k they will never match a true native image. Pretty much it runs your game at 1080 and then just tells you it is running at 4k. It tries to do magic up scaling but once someone shows you what to look for you can clearly see the difference in the image quality.

But again you can go with either choice you have for you cpu upgarde. It will make little to no difference in your FPS. Maybe when a new 5090 or whatever comes out,for $2500 of course, we can get 120 4k performance without trickery.

forget about DLSS and Up-scaling, is it worth changing my processor from R7 3700x to 5800x3d (which costs $ 317) with RTX 4090?

It is all going to depend on the exact game. Things like city simulators tends to need lots of cpu but many of those have extremely basic graphics styles. Shooter type games also like cpu but if you are true shooter player you do not run at 4k. You run at 1080 with all the settings as low as possible.....you know so you can POWN newbies.

I would play some of the game you like and use one of the hardware monitor to see how much cpu and how many cores you are currently using. My general feeling is you will not see $300 worth of improvement.
