Just a generalization of how badly Bitcoin mining has gotten that GPU mining became profitable again.

Interesting comparison.
however, where you see these prices for R9 280X?
I see ~$240 on Amazon for new and ~$175 for used.
Refurbs are ~$150

I am thinking, maybe to do some Ethereum mining for fun, but I could also simply buy more ETH.
I did buy some in early January and some after trading begun and quite pleased so far to say the least.

eBay. Took the average for the 7950/7970/280X which are the best bang for the buck for Ethereum. The brand new cards, aren't that much quicker.

They really arent, i'm not sure what's up. The only difference is more RAM, so it could mine Eth longer. But we dont know what will happen to Eth in the future and it might switch to POS before we can cap out the 280x anyways.

I probably don't know what to look for, but i don't see the prices that you mention (i see initial bids with these numbers, but nothing like this in buy it now).

Well, i just find out that my PC with the highest PSU power (300W; HP 500-267c desktop) can only support GTX 750 Ti, but not R9 280X.

If you guys know, would it be easy to hook up Corsair 500 or even spare EVGA 1300 to the card?
I never did anything with GPU cards before, so please forgive my newbiness in this department.
maybe something new to play with as bitcoin mining is getting depressing lately.

Depend what the card is but i run a 5 280x rig on one 1300. Multi PSU is not a problem with the mobo connector y splitter or you could also power everything at the same time using the surge protector switch.

For the price, he prolly refer to this;
http://www.ebay.ca/sch/i.html?_from=R40&_sacat=0&_nkw=r9%20280x&LH_Complete=1&LH_Sold=1&rt=nc&_trksid=p2045573.m1684

As you can see it comes down to about 160$~ Shipped.

I understand what you want to say, but your comparison is not entirely right.
First, you compare used card with new miner. Prices for such used cards are mostly higher.
And Antminers are usually rock stabil - this is not possible to say for GPU mining (I had in the past various 200 GPUs).
I had a lot of defective cards, very often I had switch on/off my GPU rigs.
Also GPU rigs are not so compact as Asic miners.

[Cashew]

Don't worry about this. This is not only Bitcoin which is bad performing but also Ethereum which is rocking. Bitcoin will be back at the halving !

Wat. S7 used or new is same price, we can take a Used S7 priced at 800$ too if you want. And i dont know what you're doing to your GPUs but i got 0 failure in years. We can also take the price of a brand new 280x if you want, which is only 40$ more. The math is roughly the same.

[VirosaGITS]

Eh maybe I should turn my amd rig back on, that or see if the maxwell cards I have been stocking mine it as well.

Well you missed about 3-4 months of good profit with them tho. The thing with Maxwell is they work fine but while they take half the power consumption they also hash at about half speed. So you're left with a low $/GH ratio.

But if you already have them on hand... yeah check it out.

[adaseb]

The prices might not be exactly accurate but the point I am trying to make is that a GPU is cheaper, quieter, less power, makes the same amount of $ as an S7, and will retain higher value most likely with the halving due.

Most people these days can't even mine with 10 cents power but with a GPU its still possible. And if you buy a brand new GPU for $300, in one year it will still be worth at least $150, If you pay $3000 for an ASIC in one year, it will be worth like $200.

Can those amd r9 gpu's be running without a computer within it?
Is only this thing needed to mine cryptocurrency, or also other things get involved?

Its needs to be inside a motherboard whic his basically a computer. You can mine any type of coin with GPUs, even Bitcoin.

I heard that if u use gpu's to mine coins, that after a few years they will be dead because it ran too long on max power.
So it basically dies, is that treu or just a story?

From what I read, the problem is not the moderate heat (like 80°C) but the temperature changes dilating and reducing the chip which physically breaks the chip.
Supercalculators run at 100% for months/years and they don't break.

I run as many as 24 gpu's back in the day.  if you underclock  and undervolt  they will last.but eth may not last as most alt coins do not last

So you are saying that gpu mining is only for ethereum, please tell me why.
I don't get it, why it is better for eth then for bitcoin? What is actually the difference?

Because you cant mine ETH with an Antminer only with GPUs.

ETHEREUM has the #2 market cap to BTC right now, its more valuable then LTC. But altcoins aren't always as stable as BTC.

Algorithms and asics, so think of it like this a Bitcoin pays for doing Math type A (we will pretend it is division) and Ethereum does Math type B (we will pretend multiplication).
A GPU can do all types of algorithms, So lets say it can solve 15 million division problems a second or 3 million multiplication problems a second. That's fine and dandy, but then comes out machines that ONLY do division and that is it.

They run the same wattage as a gpu but do 300 billion division problems a second and the difficulty of having the winning answer in time with gpu is lowered. Now it is so much lowered it is nearly IMPOSSIBLE but the amount of electricity to run that graphics card is not changing.

Now Ethereum is running the different algorithm (so again pretend multiplication) while there are no machines made to do ONLY (yet) multiplication the graphic card is the only way to do it and mine ethereum. The division machines can not do multiplication and never will.

Understand?

Nutshell version:
GPU does everything, but its extremely slow compared to circuit and processors solely designed to hash a specific instruction over and over. There are no ASIC for Ethereum's algo, therefore GPU is very profitable for it.

i wish that was the case with btc, as we are wasting a lot of computations on a very few transactions.
basically, ~5th/sXday/transaction or one S7 running the whole day to do ONE transaction.
