Upgrading from a 3070, 4080s? VR gaming

Gibbo3771 · 19 Jan 2025 at 19:35

I'm wanting to upgrade from a 3070 to something and I'm thinking the 4080s. I actually don't play very demanding games however I do sim race exclusively in VR. Unfortunately even in iRacing the 3070 just isn't cutting it with my Quest 3, especially when it's a wet race. I'm also looking to purchase a Pimax Crystal Super this year and I'm aware not even a 5090 could max out this headsets potential but the clarity at that resolution is worth dropping the settings down. I don't think there is any point in holding out for 5xxx cards unless someone can convince me otherwise.

My main issue is that I have a 5600X. At this point in time I can only afford a GPU or a CPU. Will my 5600X be OK with something like a 5600X? Am I also going to have to upgrade to a beefier CPU before I upgrade my VR headset?

Full specs:

AMD 5600X
64GB DDR4
Strix B350-F
750W PSU, I forget which one but it's a gold rated Seasonic

I don't upgrade often and tend to just ask here and go with the general consensus. I can no long rely on asking places like Reddit because the attitude of the users + the number of bots is ridiculous

.

Thoughts?

what exactly is your budget?

my gut feeling is that a 5700x3d AND a 4070 TI super, would be better upgrade than just a 4080 super alone
(i've got a 5800x3d + 4070 super in my secondary rig)

it looks like you'd want the cpu upgrade to an X3D chip
(clip is for the 5800x3d, i'm guessing the 5700x3d is not too far behind)

Nice benchmark find.

In terms of budget, pretty much anything that isn't a 4090. I just can't justify the absurd cost of that. I was not aware there was a 5700x3d so I could swing that pairing just fine. I'm just not interested in paying double the cost for 10-20% gains because I would rather just reduce a setting or two and spend that money on my actual car lol.

in which case then i stand by my recommendation of a 5700x3d with a 4070 ti super (the benefit is that you do get the 16gb vram that was not on the non-super ti)

The RRP for the 4080S is $999, the 4070ti $799, the 5080 is the same as the 4080S and the 5070ti is $749, so $50 cheaper than the 4070ti. Generally nvidia just concert to £ on a 1:1 basis, but really at the same pride or a touch cheaper for the t070ti, why get a 4000 series, unless its discounged heavily.
From all leeks raster is 10-15% better (30-35 for the 5090) , and dlss4 isnt fully backward compatible. Saw pccentric test the5090 with cyberpunk. He culd test it how he liked it, so froed all the settings. I was fairly impressed. Whatever ai algorithm theyre using, its working. Thecfull frame gen actually had a latency which was playable. Id actually bectempted toctry it myself, which looking from vids of 4000 series doesnt interest me at all..and its game like flight/sim racing where that stuff works very well
Sorry on a really old tablet otherwisexidxlink the vid...butvid try and get a fe 5000 card if i were you, if def upgrading now

Vid below shows the new 5090..sorry, haven't seen any on a 5080 yet, but allows him to film any setting he wanted..and he also shows the latency while using FG so you can see how well it does..remeber, you wont get this on a 4000 series gpu

your setup will all be about the gpu..the faster the better. remember vid above is using a 1440 ultrawide, so pushing 4.9M pixels... your pimax crystal super headset will be pushing 29.5M pixels(3840x3840 per eye or 14.75m pixels per eye), the equivalent of 3.5 4k screens, or the equivalent of 6 of the above ultrawide screens together. At this point the heavy lifting will all be on the gpu, and the cpu will be having a much easier time of it. I'd be pushing maxing out your gpu budget above everything else, as this will be the most expensive/important part of your setup

Another good video thanks! Fortunately I doubt I will be running max settings in any VR racing game so I'm not sure where that sits me. I am curious if iRacing can run at full in VR as it's not uncommon for people to run triple 2k/4k monitors. I'm 100% happy taking a visual quality hit for a crispers image, playing on the quest for 3-4 hours is quite tiring and on the index it's even worse.

at 29.5M pixels, running anything at max settings is an achievement. I'm just saying for me, I'd be looking at thje best upscaling and maybe FG for that kind of pixel count, and so has to be high end 5000 series cards.

below is the 5600X v 5700X v 5700X3D...last game is F1 and the 5600x and 5700x beat the 5700X3D...the higher the resolution the more work the gpu has to do, which takes pressure off the cpu. Because of that the extra l3 cache the x3d cpu's have don't matter as much, and actually the original x3d cpu had lower clock speeeds, prob why the 5600x and 5700x beat it in the game. Admittedly it's a 3070..a 5080 will be a different beast, but I'd rather buy a 5080 than a 5070ti and a 5700x3d... I think the gpu has to render so many pixels, an x3d cpu will have no effect. Better saving and jumpinbg to AM5 and getting a newer cpu with a much higher clock speed..that'll make more of a difference to you I think (a ryzen 7600 on av beats a 5700x3d in gaming anyway and is cheaper, and is bottom of the stack for am5...I'd put money into gpu, save bit more, then down the line, sell the am4 rig and put towards am5...you can get a decent board for £160, 32gb 6000c30 is £100 and a 7600X is less than £200..actually is you don't mind importing, seen the 9700x for £230)..unless of course if you can get a cheap 5700x3d 2nd hand..new has dropped to £200, but that's still a lot for an older cpu now

and 7600 vs 5700x3d...4k on the right

new post as run out of room....I was quite suprised with the 5090 demo he did of cyberpunk at 4k...getting 256fps 4k upscaled fg with latency 50ms or so for full ray trace pathtracing everything max..pretty impressive stuff, as pure raster was 29/30fps...and looking at pic quality was pretty impressive too
and before anyone goes 29/30fps raster is crap, the 4090 managed 17/20fps (looked that up on a seperate vid) doing the same thing in raster (cyberpunk path tracing is just so demanding on the gpu)

i think is the fg scales in the 5080, I think you'll be quite suprised how goos the render quality will be when you play

I'm not sure how that transltes to VR, luckily the Pimax is a wired headset so it's most likely whatever it is on the flatscreen. However I'm not sure how that compares to what I have now. With the 3070 and the Quest 3 I can hit 90fps for the majority of a race so the frame time is around like what, 10ms (gpu time) + 35 (headset latency). So moving to a wired headset reduces that latency to practically nothing so if I'm able to hit 90FPS with 10-15ms frame time that would be ideal. That means I'm at the mercy of the server ping and not my hardware.

To put into context in racing, if frame rate fluctuates say from 90FPS to 60FPS (which it does now when it rains) it moves the braking zone by 1m at 60mph and almost 2m at 120mph. This isn't an issue if you're in the front of the pack with a bit of space but if you're midfield or behind someone it means you have to take into consideration hardware latency, your ping and their ping. Not easy to do with inconsistent framerate

.

Long story short, I am going to need to drop the settings regardless of card because like you said nothing is going to run such a headset at max settings on a highframe rate.

The odds of me finding a retail priced 5080 is probably slim to none and used 4090s are still going to be north of £1k. Or do you think otherwise?

I'm not sure, 4000 series launch wasn't spectacular. this time round I've read less being offered and might be more demand just from the volume of people that bought the 3000 series as was peak crypto/covid, so may be more people that have pc's and want to upgrade..me included as driving a 3070ti for 4k...think they'll be a llittle time to pick one up..
think either fe (you know where to go for that), or you'll have the msi ventus (looks a bit to plastic for me, I'd rather pay a bit more for the inspire model), gigabyte windforce or zotac supersolid..sure their more but these should be rrp models. I'd take a look at one you like look of and then just go for it on launch...don't hang around umming and erring. I did that with the 9800x3d..so from £450 to £530 now...don't expect pc parts to be rrp anymore..if popular they just go up in price. shops will scalp you just as much as a scalper

below are a few you can look at though as an idea

the zotac cards so you can see the solid
