Am finding my RX 6600 is not cutting it for VR.  Using MSFS and may try DCS at some point.

Current System I5-9600K, 32G ram, 1T nmve, 1T sata SSD, 650 Watt PSU (will upgrade if needed).  HP Reverb G2 V2.

GPU's considering:

RTX 3080 10G (as low as 750 USD)

RTX 3080 12G (about 800 USD)

RX 6900XT (about 700 USD)

RTX 3080TI (cheapest one on Amazon is 870 USD)

Looking at Amazon and Newegg.

3090's are outside my budget, especially considering will probably need to buy a PSU.

 

So what say you all and thanks for any responses.

 

I can recommend the EVGA FTW3 Ultra 3080TI. I would stay away from the 10GB RTX cards.

Before I built my new PC I ran it for a day with my i5-9600K and it was a definite upgrade from my 1080TI. You will definitely want a new power supply, 850W should do. I had it running in my new PC and the i7-12700K is a better match for it which I was expecting. A friend brought my 3080TI yesterday and I found a 2 month old EVGA FTW3 3090 for $1,200 CDN which is the same price I paid for my 3080TI in June (that was brand new from  a private seller too). I checked with EVGA and they confirm the card hasn't been registered and there is no problem with me registering it for the 3yr warranty.

Here in Canada there is a ton of GPU's for sale that haven't been used. People brought them thinking they could make a profit and the prices are really coming down. Have a look locally and see what there is, you might be surprised.

I am just doing some testing and the 3090 is performing really nicely, I am seeing an improvement over the 3080TI. 

Your going to be CPU limited with a more powerful GPU and you will not get the full benefit.

100% correct,

When I tested my 3080TI with my i5-9600K I had to limit fps to 30 which did allow me to push the settings higher than what my 1080TI could manage while still giving my 9600K time to catchup. It is not an ideal pairing but doable.

Thanks for the advice.  Do either off you guys do VR?

The point he is making with todays 3090 even with the fastest CPU you are loosing some GPU performance in flight sim, as they are based on years old code even MSFS the CPU is still the running the show, the newest games benefit more from the new GPU`s. Upgrading to the next gen CPU will be better than the next gen GPU.

No sorry,

I just run full 4K on a 43 inch TV. I think if you are looking for VR you may need a stronger CPU although I could be wrong. The best thing you could do if you do upgrade the GPU is to lock your frames to 30 and make sure you put as much load on the GPU as possible. Stutters will be introduced once you start getting Main thread limited. If you can keep that from happening you will get a much better experience.

If you really want the best from something like a 3080 or 3080TI you will need a stronger CPU in the end. Even with an i7-12700K & 3080TI I struggled to maintain 60fps in complex aircraft with high to ultra settings. Yesterday I did some testing and a 1.5 hour flight in the PMDG 737-600 and I started with the high end preset and a few Ultra settings with TLOD & OLOD on 150 and with the 3090 & i7-12700K I did actually maintain 60fps, it dipped here and there to 55 - 57 but overall was pretty consistent. I couldn't quite manage this with the 3080TI without dropping settings further. Obviously each PC is different and your mileage may vary. If you just fly less demanding aircraft you would have a better chance.

Have a look at this thread over on the Microsoft forum, it is quite a good approach to dialing the sim in but at the end of the day you need a CPU & GPU that are well matched.

Good luck

You might have to get a PSU with a 3080TI. I did. Whats the rating on yours?

Rick

My PSU is a 650w.  Looking at online power calculator with my current system and a 3080 puts me at about 600ish load, cutting it kinda close.  The GPU operating at stock TDP of 350w.

I understand about load balancing between CPU and GPU in MSFS using Dev mode as I am currently getting about 35FPS in VR over the Southern Califfornia area (US) testing with the FI Spitfire, but that is with all low settings and creative use of OpenVR toolkit and DSR scaling.  And the Spit is not that hard on frame rates I think.

If I increase settings I get severely GPU limited with the RX 6600, which is why I am thinking or replacing the GPU first.  CPU and motherboard later.  My VR headset resolution is 2160 per eye, so basically 4K. 

At this point I am thinking 3080 12G, seems to be almost a TI per benchmarks. 

Anyone have experience with the AMD 6900XT with MSFS?  Benchmarks seem to compare it with 3090's, and they are 699 at Newegg right now. 

Used was mentioned but around here the prices seem higher than new at the moment.

I have the 6900xt and the performance is outstanding, but do not get anything less than the 6900xt though (6800 isn't worth it to save $100, as it is much slower). The AMD Adrenaline software they come with is a nuisance, it's a love-hate relationship, some of it is good but it will reset your custom fan settings, though it happens less after you get everything optimized.

I don't have any stability issues after replacing my Power Supply, I did an 8 hour test flight. Though DX 12 still has issues in MSFS, but that is why they call DX12-beta probably. AMD doesn't have DLSS, but I don't care about that.

If I had to do it all over again, would I spend more for the Nvidia 3080 TI or 3090, nope I am very happy with the AMD 6900xt and will only sell it later after the 4000's are out a while, and if I feel like I need it. The software does drive me nuts sometimes though, but having 16GB GPU ram with this performance level for $700 is amazing.

I keep mine underclocked at 5% to 10%, using only air cooling my max temp I've hit is 72c and it averages in the 60's even with high load.
I have 4 noctua fans in my case. The VR performance is very good and works great, but you must use only one specific driver version for now (22.5.1).
I have both the G2 and Quest2, and they both work fine once you get the software issues sorted out.

Your P/S is too close to the rating, the problem is as power supplies age the power spikes aren't handled as well. Even my 8 year old 1000 watt had issues with the 6900xt's spikes, though I did have 7 drives connected and 14 USB devices (but still).

Get an EVGA 1200 watt Platinum, specifically I recommend the EVGA Supernova 1200 P3, 80 Plus Platinum 1200W

Your passmark is 10,785, you need a new CPU and GPU, upgrading one or the other will not bring the full benefit.
Your single thread rating is 2780 which is decent, but it is pointless to spend all the money on a GPU and not upgrade your CPU and power.

I only paid $160 for the 1200 watt EVGA, Amazon ran out of stock I guess or took them off sale, you might want to wait.

Either that one or the AMD 6900xt will both work fine, the performance will be similar, but AMD is +4GB memory, not that it matters that much, but it might eventually.
You cannot trust any of those FPS tests on Youtube, they are all horribly inaccurate, but my gut feeling and based on testing is that the 6900xt is faster in VR than the 3080.
If you run both cards at default, it's probably a tossup though. Underclocking AMD's drops the temps pretty low, and you don't have to underclock that much.

Just saw Gamestop and Amazon has the PNY 3090 for $1050, if you are debating a 3080 vs. a 6900xt, then I would take the 3090 over both, but sounds like it'd be stretching your budget. For a budget choice, the AMD makes more sense. PNY is a good company and similarly to EVGA are very easy to deal with on warranty issues (at least when I had one a couple years back).
