    6800 XT Red Dragon Timespy, even better than the Red Devil score.

    Fairymuff. I'd heard they were pretty solid for altcoin mining, happy that's not the case.

    Still not sure which card I'll keep though... 3070 is a bit of a weapon for it's price when you factor in a sneaky OC, DLSS and Gsync.

    I mine on my card, it's generally the Ethereum algo that they mine. At the moment it gets around $5/day, has been roughly that or higher since the btc resurgence. I get around 70Mh/s at like 675Mv, 2150 memory on fast timings, power draw is 130-140w and temps are like 45c idle fans. Ampere does better because of the higher memory bandwidth, somewhere around 100+Mh/s but uses a fair bit more juice to do it (~50% per hash unoptimised). Turing is about the same - my 2080 Ti also get about $5/day but at ~ 200-220W draw (I usually run it lower than this though for a bit better efficiency).

    I have a 6.6kW solar setup and excluding feed in and surplus I pay an average of 18.5c/kWh, the average is actually even lower as I schedule in peak sun and off-peak power (14.5c/kWh). I mine when profitable to make a little bit of extra pocket money for computer components, to buy stuff from EK/newegg/Storm. My 6900XT, 5950X, water cooling and memory were all paid for with BTC

    Yeah but having solar helps, without it you'd probably be losing money, $5 a day is nothing really when you factor in total system draw. Weren't the older AMD cards way better a mining as well? Suppose with bitcoin prices going up Ethereum would be getting harder and harder to mine.

    On another note 6900 XT from my friend is on the way, express so might get here tomorrow :leet:.

    I'm pleased seeing all these 6900 XT's <3

    If you were attempting ROI on the price of the GPU then it would be a real struggle, but as a hobby when the card is not in use, the PC is on anyway etc, it's not a great expense. If you call the rest of the system ~ 100w, so say 250w? Even rounding up to 300W because of a terrible power plan, browser left open with idle usage, etc, 0.3x24=7.2, 7.2x0.185 = $1.35.

    So for me it would be profitible even without the solar, and even with it I do have the mining cut off when <$2, which it rarely is. I also don't have A/C as a factor (which is a big variable) the nights are cool and I generally have windows open in summer. For you mainlanders with your expensive electricity and high ambient temperatures, the margins probably arent worth. Factor in the Tasmanian winter and these little IC's are very effective at keeping the house liveable without needing additional heating so that's just all profit :p.

    Have you tried multi monitor with the usb-c to DP?

    Whatever happened to the priority list Scorptec put out in late November? I reserved a Sapphire Nitro+ 6800 XT and haven't heard a thing since. Has anyone else been contacted by Scorptec to say their card was in stock?

    He has 2 monitors and a tv but I think he was only using 2 monitors.

    I might be getting the card tomorrow (express post) so I'll be able to test properly when I get it seeing I run 3 screens.

    Huge no, but I bugged them and eventually got a queue number (Mid 30's - had my original order in 2 minutes after the listing went up on the ref cards). Log into your account and ask is your best bet. Will probably take them half a week to reply though.

    One of my mates ordered some other variant and is #19, but was a couple minutes after me on the original order, so I'm guessing the sapphire cards were damn popular.

    Got my reference card installed tonight. So far, so good.

    Quick play at stock clocks with just the power limit increased. (cpu locked at 4.5GHz/1.2V)

    Now to order a waterblock. :D

    Hah, did a quick comparison on shadow of the tomb raider.

    6900xt at 3440x1440 almost matches my 1080ti at 1920x1080 perfectly. Slight advantage to the 6900xt.

    So I'm basically back to where I was a couple of months ago, just with a slightly bigger monitor. lol

    1080ti @ 1920 x 1080 - 138fps

    6900xt @ 3440x1440 - 146 fps
