    A great video card. We'll built. It is huge so make sure your cas can fit it. Even with its size it does not have a sag issue when mounted.

    Purchased this card as it was the only one I could actually get in my virtual cart. I really wanted the reference 6800 XT model but with that said I am not disappointed at all with the performance of this card. Yes it was pricey compared to the reference model of this chip but this card completely blows away the radeon VII I had previously and it does it whisper quiet. I even was able to overclock it to the max the drivers allow, 2600mhz and performance is now almost on par with the XT model. If it is all that's available do yourself a favor and get it! Was well worth not having to wait another 3 plus months for a card.

    The quietest RX 6800 on the market

    This is one of the best graphics cards XFX has ever made. I previously had the RX 5700 XT Thicc III (nice design, fans were loud during gaming) as well as the RX 5700 XT Raw II (garbage, so loud!). This Speedster Merc RX 6800 is super quiet even at full load. I was able to overclock to the current AMD capped maximum; it rivals a stock 6800 XT now. It was totally worth it at the $699 paid (not sure I'd buy it for the current $899 asking price though).

    This card was bought at 4:30 am and was well worth it. The card is quiet enough that you won't notice it even during heavy load. The frames outputted on this card is what you expect from a 6800 and haven't had any problems with it and also experience any of the AMD software issues. The only thing to note is that this card is very lengthy.

    This thing is HUGE. Make sure your case can fit it. It is 13.5" long. For as long and heavy as it is, I saw very little slag with it. Build quality is great, quite and cool. Unfortunately, I had issues with this one as it did not do very well with my main game which is Destiny 2. I saw stuttering, game freeze and FPS down to 10. What a bummer and had to return it. This is using their latest driver and used DDU to uninstall my old driver prior.

    This card is absolutely insane. XFX did an amazing job with this card. This Is hands down the best air cooler on any card. Extreme overclock potential. Highly recommend avoiding reference cards since the 6000 series has high overclock potential. This card is gorgeous except for the Merc 319 logo on the back but hey maybe you like that.

    Didn't expect to be impressed but mine overclocks to 2550MHz core at 980mV and set a RX6800+Ryzen 2600X Timespy world record at 13660. Unfortunately this was way way over MSRP.

    Great card to add to my new gaming PC. This works great for CyberPunk. Installed easily and posted right up. No problems or crashes to date. The only problem I have with the product is raytracing is still not supported in cyberpunk.

    Solid, Powerful Card for Everything Except VR

    Got lucky on a huge BB drop in January and managed to get this in my cart and purchase. Had all parts gathered but GPU for a high end build, so was only hunting the higher end cards. Once purchase confirmed, I looked at specs/reviews on this card and all were stellar. Began my build as soon as I got it home No initial problems with the card other than did not include power cables it claimed were included. My PSU only had the split Y cables, so had to purchase cables separately. Tried to get XFX to send me the cables since the box claimed they were included, but in the end they just sent me two Y-split adapter cables; completely useless to me. Built my rig to support both a powerful video editing program and high end VR gaming. Unfortunately, this card (or could be drivers) cause my flight sim to crash to desktop on low-to-medium settings. A card this powerful ought to allow at least high settings in the sim if not ultra, but its drivers don't seem to be very good playing nice with VR. Considering the extreme difficulty of replacing this card, I am forced to keep it for the time being. Having said all that, the XFX 6800 is a very good card for 2D gaming as well as up to 4K video editing on a powerful editor. It has no problems whatsoever running games/video editing in 1440P at 144Hz refresh rate. So if you don't really care about VR gaming, I would highly recommend this card as it is a 'beast' in all other areas. So far it's been a very quiet card and temps never get higher than the mid 70s range (C) and has scored very well in the "Heaven" benchmarking tests. Maybe when new driver releases begin supporting high end VR, I'll change my mind about replacing this card. Time will tell. Bottom line: Highly recommend for video editing and 2D gaming ONLY. DO NOT BUY if you plan to do any high-end VR gaming, (for now).

    The card looks like a beast but is not fast enough for what I want to apply it for I needed the XT version. It’s massive to so be careful if you have a small case and buy this card.

    Returned after having multiple issues. I think the card is powerful enough, but kept having system issues and hangups despite updating every driver/bios possible. Not totally sure if its an AMD software/driver issue or not. Not worth the hassle for a 900$ card. Replaced it with a 3060ti and I am much happier. It never would load CoD properly and the 3060ti performance in World of Warcraft is surprisingly better at 2k with raytracing. Its a beautiful looking card though.
