Absolutely beautiful, but beware of coil whine

I watched many reviews on this particular card, but none showed how handsome it is. One of the best looking cards on the market. The build quality is top notch, and the cooling solution is really over-built for this kind of card. That's a lot of headroom for overclocking. The default fan curve is setup for minimal noise, the fans actually don't spin with light workloads like browsing, and they're reluctant to spin fast on a stress test This makes the card run a little toasty, but you absolutely have the options to prioritize thermals over noise. This kind of flexibility is welcomed.
Now this card would get 5 stars if it wasnt for the coil whine. I don't know if my card is a lemon in that regard or its a particular problem with this model, but the coil whine is there when the card is under load. Placing a frame time limiter solved it for me, but if you play high FPS games this might not work for you.
Overall great card, looks beast, great cooling, but that whine..

Super efficient ETH mining card

I am using this card for the sole purpose of mining ETH. As of September, it is the most efficient card for mining, with a reported performance (32 MH/s hash rate) per watt rating of .43. After tweaking the clock and voltage settings, I have been consistently mining for weeks at 31.84 MH/s with no crashes. Power consumption is only 54W according to AMD software, so its likely around 70W at the wall. Even with ETH's upcoming change to proof of stake, I highly recommend buying this card in the $400s.
I have no comment with performance in respect to gaming or other GPU heavy applications.

Cooler is a bit overkill on this GPU, but it does make this extremely quiet and cool. Can barely hear it in my system. High build quality and feel, performance is decent for the price.

6600xt is a solid buy. Got mine day 1 for a
slight discount. Three fans keep the card running nice and cool while quiet. Needs only one 8 pin power

This is a great looking card and decent price compared to other brands. Cooling is overkill but it is super cool I guess. Great for 1080p.

These cards came in significantly over MSRP, but they still out-perform a 3060, and are cheaper. Until the chip shortage is over, the 6600 XT is going to be one of the best values you can get for entry level gaming.

This GPU would be perfect if it didn't have coil whine. It's low energy but gets pretty good performance. Besides the coil whine, the fans are quiet.

Got this card at launch for under 400 and now its 700. The card works flawless and performs well. But no where near a 3080 for the same price point
