It's a good card, but there are some nuances that are important to know.
10 January 2026 
First of all, it should be clarified that XFX's range of cards, from the lowest to the highest, looks like this: Swift -> Quicksilver -> Mercury. The first two are essentially the same cards with different heatsinks: Swift is wider, Quicksilver is longer, that's it. They have the most basic factory GPU frequency. Mercury is XFX's top line of cards, offering the highest overclocking, massive heatsink, the largest in fact of all the 9070 XT from all manufacturers, and it includes a vapor chamber... but all this concerns the Mercury OC version. All the videos on YouTube from the major channels will discuss and test specifically the Mercury OC version.

However, this specific card is quite different. So, differences from the OC version:

1) There's no vapor chamber here
2) It has 2 power connectors instead of 3, with a base power consumption of 304 W
3) This card operates at factory base frequencies, meaning at the Swift/Quicksilver level. I even suspect that it simply uses the board from the lower versions (the main difference being 11 power phases instead of 13 and the already mentioned power connectors, but it’s not overclocked).

Thus, essentially, this specific execution is not a flagship, but a basic model with better cooling than the other two versions. It's important to understand that although it's "cut down," the cooling here is still better than in the Swift/Quicksilver versions. And even they are quite cool. The loss of factory overclocking compared to OC versions is a maximum of about 5% in performance.
About temperatures. My card has Samsung memory, not Hynix, but this is random and depends on the batch. Hynix runs about 8-10 degrees hotter in terms of memory:
- Stock settings.
GPU 60, hotspot 78-80, memory 72 (though it can reach 80), fan speed 1600. The card is admittedly quite noisy.
- 15% power reduction through Adrenalin.
GPU 58, hotspot 75, memory 70 (still peaks to 80), fan speed 1200. The card becomes less noisy, losing about 2-3% performance.
- 30% power reduction.
GPU 55, hotspot 65, memory around 70, fan speed 850. It enters the 'background noise' category, but loses another 5-6% performance.
Additionally, everyone generally says XFX card fans are too aggressively tuned and it makes sense to lower it a bit, but I haven't checked.

So overall, the card is quite cool. Reduce power consumption by 10-15% and slightly lower voltage (mine is stable at -50 millivolts), and you'll get a cool, relatively quiet card, even slightly more performant than out of the box. Get it if the price is just slightly more than the entry-level versions. If the price is similar to OC, it's probably more logical to choose OC.
On the downside, personally, it's not important for me with my closed case, but I would note its not particularly attractive angular appearance + the lighting is only white and shines downwards at an angle. If this is important to you, keep in mind (other Mercury versions have RGB lighting, this one only has white).

It's a bit noisy in stock, and the sound is clearly lower than the case fans, slightly humming, so you will hear it in any case.

Also, my particular unit had quite significant coil whine, turning into squeals already at 100+ fps, so it was returned to the store. But this isn't a defect and is a complete lottery, it can happen with any model from any manufacturer.
