    This is why when you sell, you should sell on US currency exchanges. In fact, you should also look at the prior 2014 statement from the treasury and the 2016 statement of tax treatment by the IRS. https://www.treasury.gov/tigta/auditreports/2016reports/201630083fr.pdf ; https://www.irs.gov/pub/irs-drop/n-14-21.pdf

    To date, it has been treated as income to the miner, but as investment property subject to capital gains rates by investors. I'll dig into the SEC announcement later today, but even the contracts with mining organizations MAY count as investment contracts, subject to the securities laws and regulations (see https://scholar.google.com/scholar_...C+v.+W.J.+Howey+Co&hl=en&as_sdt=4006&as_vis=1 - SEC v. Howey).

    I didn't see that they provided guidance (work and my nieces and nephews have been here since a day or two after that release). I'll dig into the actual release, not the reporter's understanding of the document.

    Edit: The second I start reading the articles you provide, they mention Howey. I pulled that from my head.

    So, from just reading the articles, it seems the issue is they were exchanging something of value (ether, money, etc.) in exchange for tokens (instead of stock or similar documents which are required to be registered in certain circumstances under state blue sky laws or under the Securities Act of 1933 or the Securities Exchange Act of 1934). Those tokens were to increase in value due to the investment and use of the money and property deposited with the venture, to be managed and used fully under the discretion of that venture. The Howey test has four parts, roughly:
    1. It is an investment of money
    2. There is an expectation of profits from the investment
    3. The investment of money is in a common enterprise
    4. Any profit comes from the efforts of a promoter or third party
    Just looking in a cursory fashion, there is no wonder why the SEC ruled as it did in this case. It doesn't apply fully to other applications of crypto, necessarily. This is why one does need to be careful, though. So thank you.

    Sorry, but to make sure it is seen, I'm using a second post. Here is the SEC's findings on the matter: https://www.sec.gov/litigation/investreport/34-81207.pdf
    This release will give the exact rationale used (I just found it and am starting to read it).

    Once a video is posted, request it to be moved to another thread if you think the content requires it, don't double post :)

    The video is primarily a use case for ThreadRipper and the build, about 1 minute was comparing previous use cases performance against the new build.

    The comparisons aren't vs. because you aren't going to run the old method as it's antiquated, so it's only a historical comparison, not a vs. :)

    I know what you can do on Tapatalk, and everyone else that uses Tapatalk, turn off those damn "Sent from my POS device" sig's, so I don't need to select them and delete them every time I reply to posts made via Tapatalk. :p

    There isn't a search box on each "page" in Tapatalk? You'd think the thing would provide access to site search.

    While you are checking the help info for how to disable the sig, check for search info :D

    It's going to vary depending on the OC, and so far not enough info has come around to fill in the blanks, watch the video reviews and articles for more info, or maybe someone here with their new ThreadRipper / i9 setup can post their results.

    I replied here because this is the ThreadRipper thread, that was the "New GPUs" thread. :)

    3461 1950x @ 4.0 GHz. It looks like I said early on with overclocking 3500 scores in R15 are not unreasonable. Can't wait for those better coolers to come out and some further bios revision tweaks.

    Those power draws! And with the hash rate being seen between 30-37MH/s, miners won't want them (the RX 570 can do around 30MH/s@150W). So, I'd have to say, with some reviews seeing 400-500W, not that worth it.

    What is funny is the cards are already sold out at Amazon and Newegg. After seeing current hashrates, no way is it worth it, although what is funny is getting more performance from the power saver setting than turbo:

    Do you mean holding back Mining performance? It's much lower than leaked, but more in line with what was expected, I'm thinking the leaks were BS. :)

    From the one Unboxed Hardware review I saw with charts of the averages for the RX Vega 56 across a bunch of games, it is hitting the expected 1070 performance. Note he used "faster" AIB Nvidia cards vs the reference AMD RX 56:

    Here's information I was able to pull for Vega 56 undervolt:
    http://www.gamersnexus.net/hwreviews/3020-amd-rx-vega-56-review-undervoltage-hbm-vs-core

    So, undervolting reference Vega 56 appears to cut power consumption by about 55W, stabilizes clocks, and seems to improve performance.

    Granted, partner GPU's will likely appear with better silicon and capability to adjust voltages to lower levels at stock than reference cards.

    I still think its a good GPU... if not a bit late, with a whole lot of potential that needs to be utilized by developers to maximize performance - at the moment, Vega seems to be more or less brute forcing its way through games, whereas Nvidia does not (of course I could be wrong).

    Plus, AMD can probably improve performance themselves via drivers as well (not as much as developer optimizations of course, but still).

    So based off what I have read and watched thus far, the RX Vega 56 is the card to get. However, if you are looking to spend 600+, Nvidia has what you're looking for. I know drivers are going to help a bit but at the end of the day, Nvidia knew the 1080 TI was going to be beyond what Vega could compete against.

    I guess my friend's Ryzen 5 build is going without an AMD GPU. The 580 (8GB) cost too much and while the 56 would be the card to put into his build, he can't afford $400 plus a bigger PSU (I'm putting in a 550W PSU).

    Paul's Hardware is the only review I've seen so far that has figured out how to Overclock the RX Vega and his first video is only for the RX Vega 56 but shows a nice OC bump :)

    Dude!! Bump up the PSU and get him that RX 56, that'll be sweet...hey are you sure he needs a bigger PSU??

    Hardware Unboxed found the RX 56 had a lower Total System Power requirement than the RX 580, and at only 331w total system power for the system + RX 56, that's well within the safe range of the 550w PSU you are using.

    Besides both 1070 and 1060 are high price and low availability due to mining. $399 for an RX Vega 56 might be a bargain in comparison.

    Please don't give him a mixed mash AMD + Nvida :)

    Update: Paul's Hardware found a similar total system power at 314w at stock, with RX 56 OC system power average of 386w with a peak of 487w, so maybe getting close if he wants to OC, 600w PSU? :)

    That's his build. I promised him I will build the best PC he could get for 1000 or lower. He's a student, so he can't afford more than that. I am still tweaking the components (for example, the case).

    The PSU will need to be upgraded based off what I seeing for efficiency if I were to convince him of the 56.

    I'm with the best from all of them, not oriented to one technology or another, respecting all technologies, they are providing us many technologies that we are enjoying using them for decades.
    The best always should win. My opinion, The winner CPU is the Threadripper, and the winner GPU still GTX 1080Ti, nothing super from AMD yet.

    I am likely using a mixed build of 1950x and my titan x pascal. Vega is a failure on both mining and gaming front. Vega 56 is questionable imo but I can see a point for it. Not sure if there is any for Vega 64.

    Regardless of Vega, AMD have a success with threadripper and it have produce a good CPU that I will be happy to buy.

    How many people need or will buy a 1080ti vs getting a 1060 / 1070 / 1080? I don't need one, I can live with an RX 64 / RX 56 level GPU it'll do fine for the gaming I do, and I won't miss having 10 FPS more in games. If I need more FPS, I can tune the game.

    I'm not an AMD fan boy, I am not an Nvidia fan boy, but I've bought and recommended both many times over the years.

    AMD hasn't had anything to sell in the 1070 / 1080 class, and for most games a 1080ti is a luxury, and I don't need a luxury GPU right now, I need an inexpensive RX 64 or RX 56 class GPU, and so do most people - or they want a 580 class GPU for even cheaper.

    Nvidia has had a year to line their pockets and make back their investment, now we can give AMD a chance to make back their investment.

    No charity just intelligent farming, rotating the crops to keep all the fields producing.

    Every time someone brings up the Nvidia 1080ti as the reason to buy all Nvidia GPU's, remember that you aren't buying a 1080ti if you are thinking of buying a 1070 or 1080, you have alternatives in the AMD RX 56 and RX 64.

    If you want to play with the RX 64 Water-cooled, or a partner board with water-cooling as a CLC or OL cooling system, then you get even better than 1080 performance.

    If you do buy a 1080ti, remember that there are 2 RX56's you could have bought instead, one for you and one for a friend ;)

    I have been going through EK's new Supremacy EVO Threadripper Edition CPU water block specs and I realize something. They expanded the cold plate but the chamber fins do not cover the entirety of the plate. This new design will help transfer more heat than adapted AIO coolers but I still question how effective it can be compared to a TR water block with fins that span the entire cold plate.

    I am sure we are going to get complete CPU water block redesigns in the future for TR, but I believe EK could have been ahead of its competitors if they made the change now.

    It depends, this is a really hard question to answer. Its a debate between flow restriction vs more surface area. It would entirely dependent on your nusselt numbers IMO. I mean, if I remember correctly, you dont opt for fins unless the fin efficiency is higher than 2...

    To answer this question with an actual answer, you pretty much need CFD and actual testing.

    To expand my answer, I am going to make a ASSUMPTION in that your nusselt number is going to be likely a function of your Re and Pr.(because it is the case for pipes), so it entirely depends its what I am saying I guess.

    So the GTX 1080 has no place in the world either? :)

    There are lots of people not Quantum step thinking out there. They don't need "the best", the want a good alternative to Nvidia, and the RX 64 is a good 1080 alternative.

    The place for the RX56 is assured, as the RX 56 has proven it can OC into the 1080 range - closer than a 1070 OC can get to the 1080 range, for cheaper.

    It's silly to discount the entire Vega line, which covers the rest of the 95% of the GPU buying public missed by the RX 5xx series.

    Just because there is no RX 64ti, yet, doesn't mean AMD won't happily sell to the other 95% of the public, those 5% of 1080ti and Titan Xp buyers can sip Champagne and lick Cavier all by themselves ;)

    GTX 1080 exists, cost around the same, and uses less power. Unless you need the AMD card for a specific app, I dont see the point.
