Maybe he mean problem to transfer heat from small die to cooler might be a problem, like with sandy bridge i7 CPU and lack of direct die contact

Anyway Nvidia managed to rise the frequency a lot with 16nm but still power usage is fine even with first chip on 16nm node, maybe Samsung 14nm node is not so gr8 for monolithic large GPU

There is no best GPU for mining, only altcoin with enough market cap that is mined by GPU in decent rate, atm that is ethereum which hold at least ~70% of GPU mining altcoins, if that fall profitability in instant would go to zero

and depending what algo for mining that coin use you chose the GPU

Not before end of july, even 480 with custom cooling would need 20-25 days to we see in shops, so don`t get your hopes up!

Also 470 is bad binned of 480 GPU so with best of luck if you find any before august in shop, or the supply will be very low

@Marvell1
The speed of mining is OK, but the power usage is disaster, even if new afterburner or some tool manage to lower the voltage we can not know if the card would be stable and would not cripple the speed to match

Now you should try to push memory as more you can, it does not use excessive power and ethereum is always hungry for it

For instance 79xx and 280x were gr8 for undervolting but I had no luck with 290/390 sure they can undervolt but most are unstable with even -50mV

What even worse 7950 & 280x etc can undervolt on top of that NANO with undervolt can draw as low as <100W for same speed as 480x

No one expected that AMD new GPU will use that match power, also reference GPU cooler is disaster with the heat it produce, keeping it in rig of 4-6 cards you must have AC that directly blow cold air at it!

So far miners should wait for 470 but I don`t know how it can be match better with disastrous TDP, so if the 470 with custom cooler and good OC can have some decent speed and low price, it might be OK
But 480 deffo NOT, maybe for 200$ no more!, with the diff and price drop its hard to make a profit at the end!

Maybe you don`t know but you should before you make bald statement, chines exchanges atm have no fee on trade, its the main reason for huge volume, you can play all day long with LTC/BTC->CNY with zero fee at okcoin.cn and hoube!

You just need to compare ETH/BTC volume and ETH/USD at Polonix, fake/bot volume traded there is sure over 96%

Also to me smart contracts looks like a perfect way to lock as match ethereum as possible, then pump the price make nonsense and stupid contract generate profit with the pump, and then use it as pyramid scam at the end... win win situation

I am sorry to say but Bitcoin never had FORKED, no one forked mtgox!, if they fork ethereum and looks like they will, all the promise they gave is lost, same as trust!
first rule of ethereum:
"Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference."

If that rule is broken then why would anyone use it?

I have 3 cards from mychoice but from three different providers, cryptopay, bitwala and spectro coin

would be nice to know of their rules, all are on same name/email, only problem was I can not register email to open them and must use card number to login to their sistem

Sure they can recover but only if they don`t fork at all!!! they must let the system work suffer the price penalty over long period of time, maybe even again at 1$ and wait and develop

Or if they fork, trust is lost, it gone be overtaken with some clone for sure

Beware of the etehreum and mining, if they fork because od DAO, the trust will be gone, if they let 60M $ be dumped, price is gone, in any way investors and miners will lose

Is that a problem for My choice provider or just Spectrocoin?

LTC more risk and more possible gain...

yes it is, but look at VRM temp (GPU-z can show that), sometimes GPU can be 80C and VRM 110C which is not good, depending on a card design, but ETH is low usage algo, other coins are more demanding

We can`t know, but for sure its true you need 2-3min to open account, also most ppl use that bank for small transactions because fee is only % based... min transaction is 8 euro

I sand them email to add 2 way authentication, because I don`t see any mean of protection, from e-bank you can sand wire transfer to anyone, you only can set up alerts if you balance drop on sms/email

If the temperature is fine, GPU and more important VRM temp life of the card is not declined... only problem can be bad quality of fan which will fail after few years of hard work

Looks like they are quite new, its more as internet bank then conventional, they target countries with inflation and with a easy way to open a account there

some interesting view they have on bitcoin and how ppl should use their bank for buying/selling bitcoin, etc

I opened account online process is fast, basic info, prof of identity and address as any other exchange, strange verification process took about 2-3min top

Only "problem is" debit card: Debit Card issuing is currently disabled, Please contact support@wb21.com for further details.
Also under receive payments there is wire transfer and BTC tab, under deposit it say fee is 1% duno if that bitpay fee included or not

So far their e-banking is simple and basic, so far no extra security for login
also in my address I entered street name xx/yy and in system its street name xxyy with no dash (Ok my address can be manually edited so sorted the / can not be used so I used "space")

Still no extra security for login is very strange from my point of view

Where do they have branch offices just UK and HK?

would be nice to know more, do they also provide sepa wire transfer, etc, real or even hidden fee`s, bank history, prices of mastercard/visa, etc etc

Many ppl I know used ccex.io in past few days, no issues, fast and reliable and cheap, for some its instant for other wait few days, its prolly has to do with debit/electron bank card used
