Hey guess what, my friend did an article on bitcoin mining, comparing many different video cards on how they perform. He even put together a 1000W+ monster rig that generates $3600 per year!

Here's the chart that shows the total net profit over a year (so the cost of the video card itself is subtracted, but not the cost of power consumption)

As you can see, it's not worth using an Nvidia card...

And here's the power cost per year (BC would be in group D)

So for Ulic who is running two GTX 260's, he is probably spending about $400 a year to make his $360 worth of bitcoins.

Handy chart! :thumbsup:

Here's the chart of dollars per day, followed by power cost per day, so you can do a direct comparison on your card:

I'm in group B, so if I was to run my 4890 and 460 full time, they would generate $1.50 a day, and cost $1.49

:okay:

Technically you could buy a $700 HD 6990 (or since they basically don't exist, a pair of 6970's would be roughly the same price), it would pay for itself in 132 days.

Challenge accepted?

yeah the new AMD Radeon HD 7000 series coming out in late Q3/early Q4 will probably pull in some nice numbers with its CPU processing abilities.

more trouble than its worth. dont forget the costs of burning out hardware prematurely. at least you wont have to pay for heating in your place.

Too bad you can't just estimate yearly earnings like that. Difficulty keeps on increasing, which means you need more processing power in the future to generate what you can right now.

At the moment you need approx. 1725 MH/s in order to earn 1 BTC a day. Which, at the current market rate is $13.71, less than what it was when this thread first started ($14+).

At least you're $0.01 richer! :fullofwin:

Another thing to consider is that they are going to artificially increase the amount of work it takes to generate coins, as more people join the pool. So a video card that can make $3 a day today may only be generating $0.50 by the end of the year. So it will take a lot longer to pay off a video card ;)

That's what I said.

yep. ive decided its not worth my time.

the heat generated is CRAZY. i cant use anything that requires GPU power (even youtube is chopping or moving windows around).

and the increasing difficulty is shitty. jumped on the bandwagon too late :p

There will be other chances for us... :okay:

go in early to work
swap computer parts
mine bitcoins using workplace electricity
???
profit

Difficulty goes up, meaning the cost of making a coin goes up, meaning the price of Bit coins go up?

Maybe it's a good time to buy coins?

Buy Low. Sell High :troll:

Get in early, be the 1% :troll:

I dabbled with this for a very short time, so if anyone wants 0.02152907 bit coins, PM me your address..

lol. i think i have 1 bitcoin.
