Pc build for VR for elite dangerous help

[malorob]

Hi Guys need help looking at upgrading my GPU but i am on the fence as i am seeing people saying about bottle neck between gpu and cpu's

i know only so much and am hoping someone with more knowledge can help me steer more into the right direction

Current have 11700k cpu and 1080ti gpu

I was looking at the 6800xt 16gig Vram amd
but then saw for a extra $100 - $200 i can get the 7900 xt 20gig vram gpu

and as for nivida there is nothing in the same price range

So Bottle neck and what sort of performance will i get for VR current G2 reverb.
thanks everyone

Your CPU is more than good enough. Don't worry about it.

When it comes to buying a new graphics card, there's one simple rule to follow: Buy the best card that you can afford.

4070Ti should be about the same price, and about 10% faster (despite the lower amount of memory).

If you're running a bunch of 4k screens, you'll probably want the extra VRAM of the AMD card. If you're just running 1 or 2 screens at 1080/1440p and your VR headset, you'll probably want the extra performance of the Nvidia card.

Both cards are power hungry... 750W minimum PSU. Don't cheap out on it either (I'd probably go for a Seasonic 1KW gold PSU.

I have a 850w and have been checking just that when i was shopping around what sort of power usage with each card.

the 790xtx was drawing 350w where as the xt was only 270w
as for VR i will disconnect additional monitors and just run a single

cool bananas overall thank you so much.

Funky is on point: seasonic is one of, if not the best psu supplier currently.
-check if it's one of the ten-year warranty ones just to be sure; they are worth it.

Another thing is also making sure there are enough pcie lanes on the mobo, it's a silly bottleneck to hit because it's not always super evident; nvme takes a couple of those too.

Lastly there are some newer features such as A4G/BAR/SAM/SQM.
-first three are bios features while the last one is quite technical as it has to do with network, specifically "ping under load" and may require a custom router ROM.


Anyways, looks like a good build overall and it is indeed a good idea to make sure there is always enough power for the system. And more VRAM is indeed better wrt higher resolutions.


And as always before buying new hardware: read & watch as many reviews as possible.

Biggest downfall i am noticing is the car configs what it offers in HDMI or display , overseas they can offer a C port but here in aussie we just stuck with hdmi or display

i wish i could get a card with a C port so i can just use that with my G2 reverb as it is display port and C port. may make the VR run smoother .

[Planewalker]

If by C port you mean USB-C, display port is faster w more bandwidth.
(theoretically, USB-C is almost as fast but it depends)

on the U.S version of the 7900xt it has a usb c port on it but here in aussie they have just left the standard hdmi and display port. so like we are in the stone ages. not sure why sum countries get the usb c on the gpu and other countries dont.

Things like that usually depend on the model of the card, not the location. And you don't want it as your main display cable anyway...

USB-C is more suited to laptops, and about as good as DP 1.4. New GPUs are using DP2.0 which is capable of higher bandwidth, better (uncompressed) audio, higher resolution (USB-C is good for up to 8k, while DP 2.0 is good for up to 16K), adaptive refresh rate support and a few others... It's also backwards compatible with older display port devices, and is also compatible with USB-C (DP over USB-C).

Its rather difficult to become bottlenecked by CPU in VR unless you run a really old one.
VR puts much more strain on the GPU compaired to non VR, so you are usually GPU bound.
Your CPU will probably be chilling with any GPU.

For VR also the amount of video ram is important. VR usually allocates up to 2x more VRAM. Cheaper graphics card models often come with reduced video memory, while it may be enough for flatscreen, in VR the VRAM can run short and cause severe performance issues. 12 GB should be fine for most VR games including ED, but I would definetelly not go VR with less then 12GB vram.

that sum awesum tips there thanks my 1080ti was good 5 years ago with my original htc vive but now with my reverb G2 it is showings it age.

One other thing i was told was having VR more memory ram is good so i installed 32gig and it runs better than 16gig that is for sure .

But my new MB can run 128gig and i am not sure if i should upgrade that too?

[funkynutz]

Most people currently have no use for anything more than 32GB. There's a few edge cases where it's worth having (extra RAM can be handy if you do lots of video editing for instance), but for a gaming rig you won't need more than 32 anytime soon.

[ждун]

I don't think that more then 32GB of memory is worth it. 32 is already more then enough and having more won't improve the performance any further. I would rather invest more into GPU. Video ram is more important then ram for VR.

I did the mistake saving on GPU, purchasing a graphics card with only 8GB vram. That is barelly enough for VR. I have to monitor it and ensure it doesn't run full. When it runs full the performance breaks down dramaticly as it starts using hard drive for additional memory. This forces me to run lower resolution in certain scenarios. The higher the resolution the more video ram is allocated. So I would say for VR with G2 make sure you have at least 12GB on vram, better 16. 20gb vram will definetelly be enough for any scenario and would allow you to push the resolution and use the G2 to its full potential.

If you tell which one it is i can skim through the specs.
128Gb cap means that it is fairly new however so i surmise you're in the clear.

only says upto 5000mhz was kinda thinking getting two or even one stick of ram that is 5000mhz than the 4 x8 rated at 32000mhz , just not sure if going from 3200 to the 5 would help , still a work in progress. i have 3 more weeks to decided

[Planewalker]

Aorus is generally a very solid and sturdy make, and that one also runs pcie4.0 like the gpus you've looked at which is just something to be aware of.
(you can run a pcie4 gpu on a pcie5 mobo, but almost never the other way around)


Wrt available pci-e lanes and speed, it is often dependent on the CPU.
It is a good idea to check the RAM/NVME support lists too; if your new stuff is not on the list it may be incompatible. -related module P/N's are often compatible but not always.

If you check the net you will find quite thorough guides comparing 3200 to 5000 and IIRC there is a quite a bit of a performance gain. -just make sure it's DDR4 & dual channel. ;)


Here is an example of some of the fine print i've learned to look for:

• The PCIEX16 slot shares bandwidth with the M2B_CPU and M2C_CPU connectors.
  
• The PCIEX16 slot operates at up to x8 mode when a device is installed in the M2B_CPU or M2C_CPU connector.
  
  CPU:
  1 x M.2 connector (Socket 3, M key, type 2242/2260/2280 PCIe 4.0 x4/x2 SSD support) (M2A_CPU) *
  2 x M.2 connectors (Socket 3, M key, type 2260/2280/22110 PCIe 4.0* x4/x2 SSD support) (M2B_CPU)(M2C_CPU)
  *Supported by 11th Generation processors only.

As long as you make sure to install in the right sockets you are good to go.

yeah i got caught out i had the old sata M.2 and the board never support it so have to buy a separate pcie card to run the sata m.2

so that is another thing i need to upgrade get rid of the Sata M.2 and use the NVME which is onboard

so that seems like what my money will buy the 7900xt and a 2TB NVME

i am glade i have the 11gen over the 10 so many more options.
