Enough to make one moist.
Well, I imagine that's how they cool the cards... You did mean the cards, right? RIGHT?

Did they run out of Haribo?
Won't be pretty but if you insist SirI'll be getting some videos up tonight/tomorrow and over the next few days.
A picture of your system would be good too.
All sorted Matt. Thanks for the help. Made me think out the box.
Noticed the card was running a 4x PCIe in AMD's drivers hence the terrible performance. Gpu is mounted sideways.
Turned out it was my PCIe extension cable. Direct into the motherboard and it's fine!
Although probably need something more than a 3900x now haha.
Haven't done much with the card yet apart from running a few benchmarks to check stability and noise/coil whine and I was quite surprised to see that in Heaven benchmark the GPU clock was staying around 2790-2800Mhz when the official boost clock of the 7900 XT is 2400Mhz

Here'a video recording to the final tuned 7900 XTX run, recorded using the new AV1 codec.@Jay-G25 As requested, MW2 results below Extreme and Competitive Settings using the MW2 build in benchmark at 4K. Extreme uses the standard Extreme quality preset, no other options changed. HUB used the Ultra preset which is one below Extreme for reference. Competitive Settings are using the lowest settings. These are settings below the low preset in game. If you would like to download and test true lowest settings using this preset, download the config file here and place it in your My Docs > COD > Players folder. Download here.
Testing prerequisites
I am running the latest build of Windows 11, with both the AMD and Nvidia drivers installed on my setup. They work perfectly in harmony too,. My system is clean and tuned for optimal performance with minimal background apps running, aside from MSI AB/HWINFO64 and Corsair iCUE (bit of a perf hog iCue but my AIO needs it).
The 4090 is running 527.56, ReBar is at auto setting. The 4090 was run at stock settings and has been repasted using liquid metal. It therefore runs cooler by 5c+ vs normal 4090 GameRocks, the core also moves up a bin due to the lower temperatures. I am using a special performance BIOS that unlocks the power limit up to 660W (stock is 550W) and allows more performance from the 4090 vs the stock BIOS shipped with the GPU. In light of this I will set the power limit to 80% of 550W = 450W to best mimic a true stock 4090. The 4090 was run with 100% fan speed for these tests.
For the 7900 XTX, I installed the 22.12.1 driver. SAM is at auto setting. The 7900 XTX is using the stock thermal paste. The 7900 XTX is limited to a maximum power limit of 335W, it is not possible to raise it further. So the only way to extract more performance is to increase the power limit to +15% which allows up to 335W, and to then lower voltage and finally increase memory frequency. This will net you best overall increase in performance in pure % terms. The 7900 XTX was run with 100% fan speed for these tests.

@vapor matt That's about as favourable as you will get for a 4090 in Modern Warfare 2, as my 4090 is tuned to run faster than any 4090 you'll see in a tech review.

Looks stunning.
Got my Saphire XTX today. Haven't been able to get it into Windows.
Went into the bios once so it's not dead.
Asus X570 Tuf Gaming Plus is putting the VGA diagnostic LED on
Boot times can be very long with these new GPUs, wait a few mins

I was hoping to do Modern Warfare 2 next, but Activision decided to release a big update and now I'm stuck downloading for hours.
I think his issue may have been something else. I see no difference in post time on the 7900 XTX vs the 4090.

Is a 5800x3d going to be that much better than my 3900x for this 7900XTX? That would be a drop in upgrade for me, no motherboard required! I'm playing at 1440p 165hz
Caporegime
Yes a huuuuuuuge upgrade and a great match. Make sure you enable Smart Access Memory too when you get it.
3900X should have SAM, mine did.

Only drawing 335w too! Colour me impressed.
I hope my 8700k can keep up. Did a bios update earlier, enabled rebar and got a stable 5ghz oc on it now.

That’s the most it can draw sadly, expect to see that value a lot.
Are they any good for under-volting? what's the driver stress test max power when you set max to 2000Mhz and undervolt, I get about 126W with a 6900XT.That’s the most it can draw sadly, expect to see that value a lot.
