Or normal rig ?

What's a "normal rig"?

graphic card in CPU

AMD 7850 graphic card
$130 for ~400 MH/s

USB Erupter (ASIC)
$18 for ~333 MH/s

What do you think?

ASICs are only good for the people selling them. The current on the market have no ROI, the future will have no ROI once they start shipping

I think the 7850 is the only option with any hope of ROI.

So I would take the GPU over the ASIC.

 

Some ASICs are already shipping and available immediately.

You'll have to do your own ROI calculations depending on your own situation to determine if it's worth it to you.

"Standard" rigs are only useful for non SHA-256 coins, since all the ASIC chips in development/available today are for SHA-256 coins.

you'll never recover your money from all ASIC being shipped today. ASIC are only good for the people selling them. Think how many thousands of ASICMiner eruptors were sold at 2 BTC. Those people will never recover their money, but the people selling them are still laughing on their way to the bank. If you want to buy a ASIC to run as a hobby fine. If you're thinking in making money forget it.

The only profitable (about $10 or $20 a month per Gig) are the GPU miners. You can buy cheap used ones from gamer's on craigslist (if you're in the US). Don't buy new or you'll never recover your money

+1 to GPU(scrypt) mining.
Don't buy ASIC and NEVER preorder ASIC. There is guys who got their BFL with an year delay, so their only hope to make partitial ROI is to sell them... :)

I still don't get how a GPU miner at maybe $80 used for 400MH/s is better than a $18 ASIC miner that runs at 333 MH/s??

$200/GH vs. $54/GH

How do you justify the GPU being cheaper?  Even if you resell the GPU, you would eat at least the $54/GH ASIC cost in depreciation.  GPUs use a lot more power as well.

This is all assuming you're mining a SHA-256 coin. 

because you're mining ALTs at 4 times++++ BTC profitability. Next BTC diff is 200 million and who knows what the next will be, perhaps 260 million. A USB Eruptor will give you 0.00007513 BTC per day. With a 400 Meg GPU you make .01 BTC per day. Get the point? ASIC are out of ALTs (so far)

Plus electricity costs.

no way, i don't bother mining bitcoin anymore....  :-\

just investing.....

What if you use graphic card to mine with free electric?

If you have free electricity, you can try mining with a graphics card, but the probability of success will be quite low. You can still join a pool, but your returns are expected to diminish greatly over time. That is, of course, unless you have a unthinkable number of graphics cards that you picked up for free as well.

Yes, free electricity and free very expensive graphic cards, otherwise not worth the time.

pretty much. those days are over!

I disagree , im running my GPU and getting 210Mhash/s and the rewards are small , i run 2x asic miners @336.8 direct in the motherbaord and my rewards are much much higher , still rubbish of course but i cant wait to stop useing my GPU, and run some heavy mining gear when the price falls though the floor on the BFL systems , been watching ebay for 3 weeks now and they just keep getting cheaper. just my opinion guys

If i put 3 grand for a CPU graphic card mining rig , would i be able to get my cost back in half year? or in one year? what you think/

Probably not.

you'll never recover your money from all ASIC being shipped today. ASIC are only good for the people selling them. Think how many thousands of ASICMiner eruptors were sold at 2 BTC.

what about 1 year ?

Do the calculations man. It's simple math. What model processor/GPUs are you looking to buy? See what others have reported their hash rates to be. Figure out your total hash rate and use a profitability calculator to figure out how much you will make per day. Divide that amount into the total amount of money you want to spend on your rig and you will have figured out how many days ROI will take.

But I can tell you, spending $3,000 on computer to be used for mining sounds like you are being ripped off or not building it yourself (Unless you are getting some bad ass GPUs). I highly suggest buying the parts separately and building the rig yourself as you will save a lot of money doing that.

Just my two cents. I hope my message didn't convey a sarcastic or negative tone. I was merely trying to say that there are ways of figuring our ROI without having others do the math for you :)

Never ! its all custom made asic miners now

Just gave MM a [sic]. Anybody else want asic[sic].

whats a [sic] ? forgive my ignorance lol

You can change electricity price cost and hash rates when you start mining etc
this is  free power BTC always goes up 2% a month a 0% fee pool
just about everything is going your way and it still never pays off.

on the other hand I thinks its more fun that soda popcorn and a movie and cost less at full price.

With this difficulty it's only asics, with a few GPU's here and there...

Finished mining SHA256 for good, its a rat race !

ASICs are not proper for individuals to mine

explain please , also im a qualified micro components electrician so please explain why Asic is no good ?

Not everyone is getting to ASIC but buying a share to buy an ASIC that's it! Look at the Group Buy section.

the community has been ripped off by ASIC manyfacturers. Those are the one that are making a killing on Bitcoins. Every ASIC on the market WILL NEVER MAKE ROI!!!!! Stay away from pre-order ASICs, you will be ripped off and fill the pockets of techno thief's.

Yes they have a ROI, but a negative ROI.

If you are going to use basic finance terms, at least learn what they mean: http://www.investopedia.com/terms/r/returnoninvestment.asp

But if the difficulty increase stops next year as I believe, you can mine BTC back if you mine long enought. Thus positive ROI I cant rule out ;)

Bitfury-based ASICs do have a positive ROI. At least they did at the beginning of this month. I remember the times when there was a preorder on them and the price was 2000$ for 120Gh\s. If I only knew that the guys deliver, I would definitely order one or two of them back then. Now it's probably too late to do that.

There's still a possibility, though, to buy some Bitfury chips and PCBs and do the soldering on your own.

Nothing to do with the tech.
Buy one at $30 start mining get a few mBTC over time difculty goes up to the point you are making .00000001 BTC a week. 

Total value of BTC mined at that point $17.00.

So you paid $30 to get $17. That is not good.

So you paid $30 to have fun playing with drivers, mining programs and chatting on boards like this.
And you get paid back $17 that is good.

Mine litecoins with gpu and mine bitcoins with asic on same machine.  There will not be any quick profits any more unless you can get the newest asic miner before everyone else to have the advantage in hash power.  Since we are on the noob boards it probably wont happen.

No, I'll mine Scrypt based coins with my GPU for as long as it makes sense.

you can make a BTC penny or 2 a day watching videos lol

Any thoughts on cointerta terraminer IV?

Impossible to know unless you tell us the hashing power of the rig and what coins you are mining. If you have free electricity, then profitability depends on cost, hashing power, and difficulty, and nothing else.

what i think is you can get back , you are mining at there for years

If you buy used components then you can resell it back later without big loss. And GPU profitability depends on your electricity cost   ;)

I want to buy some ASIC equipment soon.

not worry about another BFL scam?

This.

Bought 2 BFL jalapenos (total cost $355 including shipping and customs). Preordered Sept2012, received in mid-July2013.  Total mined about $700 worth of BTC, sold them for a total of $1300. Investment: $355. ROI: $2000. Profit: $1645.

Now I'm out of mining, and just speculating/investing and getting more into precious metals (particularly silver).

So, if you have used the money to buy bitcoin in Sep 2012, it was around $20, you would have bought 17.75 BTC, if you sell it around Apr 2013, not at the pick, let's say $200, you would have made $3550, $3195 profit.

BFL really sucks...

Some people are for BTC mining

But as for alt coin mining not everyone is...

yeah, but still better than losing money.  unlike a lot of people i don't count "money i didn't make, but could have made IF..." as a loss.  

I don't think I can make enough money back on mining.... maybe I will look into altcoins.  :-\

But it's a lesson learned...

Oh, absolutely. A valuable lesson. Right up there with "never get involved in a land war in Asia" and "never go in against a Sicilian when death is on the line"

I am not a miner so I got nothing sorry :P

Well this first one is true, but it did not go well for the Sicilian did it?

Love that movie.

is normal rig gpu? i wouldnt buy asics at this point.
