Best possible gaming PC for high-end VR and Pimax 8KX?

Pimax Hardware Pimax Discussion

Just don’t expect the same support for the AMD cards as You’ll get for the Nvidia cards.

For example, Fixed/Dynamic Foveated Rendering is an Nvidia only feature on the Pimax headsets.

Hi Marcin,

My next rig will be based on 5950X and Nvidia 3090 if possible both water cooled on a high end 570 mobo. I guess that the best AMD GPU shown at the end of October will be only match an Nvidia 3080.

Also I consider Nvidia leading with DLSS, VRS, CUDA and RTX. I want to see if I can use ray tracing with my own created content using DLSS and eye tracking which needs VRS.

I was a long time an Intel only guy but now its time to switch. I want many PCIe 4.0 lanes as future games will directly stream from M2 PCIe Gen 4.0 x4 SSDs (see UE 5 infos) to GPU memory.
Also I need a lot of USB ports. I use StarTech cards for USB with a separate controller of each port.

@mirage335: Your LN2 cooling in a laptop form factor sounds interesting. I’m looking forward to see more.

Cheers,
Alex

Unfortunately thats the truth. On the other hand, with a 20% faster AMD GPU (which wont happen of course heh) that feature wouldn’t be as needed anymore.

I wish AMD could seriously step up their game with their GPUs so we could get some proper competition. According to the “leaks” reports so far, it seems it wont happen during this generation swap either. Price vs performance is an important factor, and in this matter Im sure AMD can take the lead again. But it won’t push the limits and wont do VR enthusiasts much favour. We still need more raw power for VR, and a lot of people would sell a kindey to get that, no doubt.

Luckily the AMD CPUs seems to push boundaries again. About time!

For me, all I need AMD to do is push Nvidia on the pancake gaming scene… :wink:

Luckily, there’s still a lot of people buying their stuff as we’d be facing even higher prices without them for sure… :slight_smile:

I’ll be keeping my 9900K for a while and buy a 3090 when available (and 4090 after that)… :smiley:

Next big upgrade will probably be a 59**X (I don’t think I’ll buy the 5950X as I don’t see a use for that many cores - so it’s essentially 250$ wasted compared to the 5900X) and a matching mainboard.

Thanks Alex. Im definitely on the same track as u are. Athough Im no expert, I does make a lot sense to move over to AMD chipset at this point for the best performance.

Especially since the “upcoming” Intel Rocket Lake seems stuck at 14nm and 8 cores. If they manage to push it beyond 5.5Ghz it may be faster than 5950X on single core by a notch, but then comes the heating issues again I suspect. Instant 80c and throttling despite water cooling. We’ve seen that before when Intel pushes its limited technology to the edges.

And USB ports yeah, no more USB PCIe cards for me. They might be good, but still such a waste of pcie lanes…

Same here. For that extra 250 or 300 bucks you can get some good fast harddrive(s), or even a mobo. In fact according to the latest leaks, the 5900X seems a bit faster than 5950X on single core. Time will tell.

It wouldn’t surprise me if it could be pushed harder… :wink:

Most motherboards don’t actually make all the CPU PCI-E lanes available… just not bothering to give you the connectors for them. Newer CPUs have a LOT of PCI-E lanes to spare in reality.

Yup and SLI is dead.

Just VR support for SLI lately. That will change eventually.

I have other use cases next to gaming that benefit from more cores. So I guess for me the 5950X is the best compromise. You can always disable HT and not needed cores to push for higher single core performance.

Thats true, but I remember initially the 10900K was limited to 16 pcie lanes or something…did they fix that?

And thats just sad I think. Such a wasted potential that could have been efficiently utilised in VR.

Is it ever going to happen? I hope you are right…

Of course I totally understand that. If I was still doing daily videos in Premiere I would go for the max amount of cores available as well.

Well, so far, I haven’t seen much evidence that it’s really worth having. But I’m not married to either company. Whichever card I think will serve me best at my price point is the one I’ll get.
cheers

I have to disagree with you… the leaks all show a 6900 series that will perform as well as a 3080, and hint that the top tier will compete with the 3090. Most reviews have been rather critical of the 3090 as being only 10-15 percent faster than the 3080, which is less than half the price.
cheers

Oh wow, you are right. That must be either because they are PCIe 4.0 lanes… or because Intel wanted to discourage server sysadmins from buying for single-core performance.

Now the real problem with that is… what are NVME users going to do? In practice, the newer CPU is probably worth it more than the illusion of ‘real’ x16 slots for GPUs, but every bit of latency does add up, and this just seems bad.

Some VR apps already support multi-GPU. The exceptions are things like DCS World (the devs seem to be extremely busy adding new impressive aircraft), and Elite Dangerous (FDev is just so blatantly lazy I can call them out with absolute certainty).

Easy answer…
Bye bye Intel…
Hello AMD :smile:

We are not there yet. Even GPU VRAM quantity is rarely important, and GPU bandwidth should only be relevant ‘between loading screens’. Any funny business with AMD’s latest CPU offering would keep them from being relevant this time around.

Intel (“desktop”) CPU’s have been limited on the amount of PCI-E lanes for a long time compared to AMD CPU’s (if You count ThreadRipper CPU’s as “desktop” that is)… :smiley:

If You go back in time though they had some nice CPU’s, like the Xeon X56** CPU’s (using X58 chipsets) but they were very, very expensive at launch… :wink:

EDIT: That said, I’m running a 9900K since I get higher clocks than I would on what AMD could offer when I bought it, but that might change with the Ryzen 5000 Series (with higher IPC). We’ll see when actual benchmarks show up… :wink:

EDIT2: A lot of the PCI-e lanes are offered by the chipsets, not the CPUs.

EDIT3:

NVMe drives are handled by the chipsets PCI-e lanes AFAIK, not the CPU’s?

Sorry but now you have completely lost me…
If I run out of GPU VRAM in VR it will turn into a complete clusterfu… of stuttering, so saying it’s rarely important when we like to push SS into 1.5 on our 8Kx’s we will run into this problem if we do not use a RTX 3090

Just wait for AMD benchmarks from trusted sources, stop overthinking it for now :slightly_smiling_face:

Man I just wish Kyle from HardOCP was still around and not working for Intel :grinning: now those where good reviews.

Well I really hope that you are right :slight_smile: Im not Nvidia nor Intel fanboy, and I would love to see some competition from AMD. Its just that I have my doubts there will be any top tier card from AMD. Why would they keep it a secret? They know Nvidia cards sell like hot cakes right now, so why wouldn’t they brag (or at least officially hint) about a top tier card if they had one coming in a week from now? Currently its all just unofficial theories that a monster RDNA2 gpu exists.

Either way, I hope Im wrong on this :slight_smile: I will easily sell my 3090 (or cancel order as it still haven’t arrived) if AMD announces something crazy next week! Even if its more expensive. Raw power is all that matters!
