I've been going over the numbers as far as profitability goes with mining and looking at a bunch of charts and it seems that CPU mining is pretty worthless. A literal drop in the bucket compares to massively parallel GPU's.

The number that just gets me is not even the cost of the CPU (lets assume you've had the computer for years, so the actual cost at this point is $0 start-up). On a Q6600, I'm only able to hit about 8.8 Mhash/sec with a power consumption of let's say 65 watts, you're looking at a return of ~$2/mo (depending on your pool and your energy rates).

The numbers just get silly, because if you're buying a rig specifically for mining and paying for the CPU, at that point it's nary impossible to recoup your money.

So my question is, when GPU mining, with the cost of power/additional cooling considered, does it even make sense to run a CPU miner from a cost perspective?

From what I have read/calculated CPU mining is just not profitable at all unless you are really really lucky solo mining and hit a block.

With the difficulty where it is, total waste of time.

I've been doing CPU mining for about 2 weeks, and I am no where near even 1BTC yet.  I'm doing it more for the fun of it at this point, hoping to get a rig at some point in the near future and actually try doing this for real.  Even then, I don't expect to make a profit on it unless the price for BTC skyrockets.  I just enjoy knowing that I am involved in something that could potentially undermine the government currency scam!

I'm currently mining at such a small MHash/sec you would piss your pants laughing at me!

AWOLRanger,

I think there are many thousands of people exactly like that, even generating slowly overtime with 10+Mhs, if the price does skyrocket over time it is worth while. Even a basic 12 month old Radeon card we tested we got 18Mhs HD5450. Plus it all helps the network!

At this point I believe you will almost always be using more $ in kWh running your CPU mining, than you can ever possibly expect to get out of it.

I wish I was getting 10+!! lol  Right now all I have is a top of the line business laptop, which means absolutely nothing when it comes to mining!  But, I do hope to get at least a minor rig in the next couple of months.

AWOLRanger,

What graphics card does it have in the laptop? Just check and see if can do GPU mining if it's a top of the line should have a Radeon maybe?? Then can switch over to the GPU, let me know and we can check that out!

What's the CPU pulling?

Unfortunately, it has an Intel HD Graphics card, and from what I've read that sucks worse than the CPU.  I pull around 6.8 when I run 4 core on the CPU.

AWOLRanger, ok no worries, would have been good if it had a Radeon in it.

Are you in America or where you based?

Best thing to do is just set a basic Rig Running a HD5850 and you'll get around 350Mhs

On our website here you can see an example,if you can get something like this and just add cards to it over time, get something with multiple slots though so you can add more cards etc and build up as you go with the initial Rig when your ready and just leave it to just mining.

When we first started looking at Bitcoins and doing testing etc, I started with just what my standard desktop had in it, then when I saw the potential of this awesome technology then decided to get into it properly. But many people are just doing what they can afford, then you see people going nuts and borrowing a tonne of money and going insane. But each to their own Smiley

I'm CPU mining for the hell of it.
but I'm in a pool and not solo.
running on 4 boxes
I'm getting about 0.03 BTC per day so what the heck. When they shift the decimal point and more people jump on board, Then were are talking some serious 'coin' LOL

Not running full tilt.
CPU's at 50%
Intel Celeron 1.0Mh/s,
Intel Dual Core 2.0Mh/s,
Intel 4 processor Xeon 12.0Mh/s
Intel I7 laptop with addressable GPU 52Mh/s

Basically for fun, and to hopefully 'Stick it to the man'

Yea, I'm in the states.  Your standard rig is probably what I would be looking for, easily upgrade-able when the time comes, and not too drastic right away.  This is more of a hobby for me at this point, so don't want to get to insane with it!

digdugg67, good on you man! thats the spirit! It's all fun, worth doing without outlaying anything!!

AWOLRanger - Yeah, if you can put the machine together or get a friend that can put a computer together something like that is perfect to start and just add cards as you want. No need to go insane. The board I would recommend is MSI 890FXA-GD70, good value for money and you can run a decent amount of cards on it.

Looks good!  So are you thinking this board with the Radeon HD5850?  I see a ton of different 'types' of 5850, is there anything in particular that I should look for there?  (I'm also partial to this case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119225)

HAHA, yea, I feel like I equate it to trying to get on the internet from my Commodore 64.  Not much happening!

it's worth it if you are doing it on 200+ systems, esp if they are multi-proc, multi-core systems Wink i've gotten to around 7ghash/s using ~256 hosts, but i've seen single accounts on eligius reach 42ghash/s.. would LOVE to know what kind of set ups they're using, 30 dual-gpu systems??

I've been using GUI-Miner and I love it.  Very easy setup, and can run multiple miner's at once.  If you go to the mining section under miner software, you can find it.  I don't know about the WinXP, though.
