I see, thanks for the explanation mewantsbitcoins!

What I mean is, if I want to do a transaction with a given person or company, what sort of assurance can I have that they are legit?

I know one developer mentioned a website that he was working on where a business could become "listed", so you could check on whether the bitcoin address given is associated with the company you believe it is associated with.  What is this website?  And is there anything else like it?

Deepbit is 10% fee with pay-per-share?  Dang... didn't know that.

Holy mother...

He's gonna have a nice surprise when he comes back then.

And he had a nice production rate too!  15k MH/s?  Dang...

But it's posted on a non-HTTPS website, so potentially, it could be at risk for such attacks as the one described.  Not likely, but hey, you never know...

Also, a forum moderator/admin could change your signature to include their own address instead, and hope you don't notice, though I suppose that a risk inherent with any posts on any forums.

I'm really confused...

In my bitcoin.exe window, I have "Your Bitcoin Address:"

I use deepbit to mine, and so I sent some bitcoins from my pool account to this address.  It went through just fine, no issues.  Then I sent those bitcoins off to MtGox.  Just fine, no issues.

But now, the "Your Bitcoin Address:" has changed to something else!  So this is not a permanent address?  If not, how/when does it change, and how are vendors able to post their address in the marketplace if it is always changing?

What's the best way to share a wallet?  Do I have to create the bitcoin.exe -server on a single computer, then have all of the other computers on the LAN connect through it?  How would I go about setting that up with poclbm?  Would I just use something like -host 192.168.1.3?  Can I have two bitcoin.exe's running on two separate computers and somehow use the same wallet.data?

Right now, I'm doing shared pooling through deepbit anyway, but I want to know all of my options, so I'd like to know how to properly set this up.

AaronM and RodeoX are already breaking that rule...

I'm from OCN.

Even more interesting is the complete LACK of 5xxx series GPU's for sale on the forums currently, vs the dozens of NVIDIA 4xx and 5xx series GPU's for sale.

Can I convince myself and get paid? 

Ok, but seriously, what sort of steps do I need to take to accept bitcoin payments?  I have a gaming community that takes donations in exchange for higher rank, and I sell my own music albums on Amazon, iTunes, etc, so I'd like to implement bitcoins for both purposes.

This website estimates that there is $4.5T of physical currencies in circulation as of September 2009.  If all of that was replaced by BitCoins, and all 21M BitCoins had been released, a single BitCoin would have the purchase power of $214,285.

I'm sure it would be several times that number if electronic currency was considered as well.

Interesting to think about...

Comparing the 5850 and the 5870...

5850 can be had for $157 shipped.
5870 can be had for $268 shipped, from a reputable seller (a few lower-priced ones that I don't necessarily trust).

5850 can do 292 MH/s at stock speeds on poclbm.
5870 can do 380 MH/s at stock speeds on poclbm.

5850 costs $0.54 per MH/s.
5870 costs $0.71 per MH/s.

It seems like, at least from a starting cost perspective, going the route of 5850's is a no-brainer.  UNTIL, you also consider the costs of a new system.  Assuming two cards per computer, it'd be $251 per system.

2x 5850 can be had for $251 + $157 x 2 = $565.00
2x 5870 can be had for $251 + $268 x 2 = $787.00

If you have to buy a computer to fit these cards, here are the new costs per MH/s.

2x 5850 costs $0.97 per MH/s
2x 5870 costs $1.04 per MH/s

So, the 5870's are still more expensive, considering initial cost, than the 5850's, even when you consider the cost for a new computer for every two cards.

I've done a lot of this analysis between various cards, and the 5850's always seem to win - at least at current video card prices.

Any other thoughts from you all?

Thanks vruce, I'll give that a shot!

SOMEONE must have set up CCC and ATI Stream on Windows before!  Come on, what are you using, and how did you get it to work?

Running Windows 7 64-bit with a Radeon 5770... I'm just curious what CCC version I should be running to get the most efficiency?

I tried installing the latest CCC, then installing the Stream SDK 2.2 (since 2.3 lowers performance), but the miner came up with an error that there were multiple versions of Open CL, and I needed to select one.

What's the proper setup for a Windows machine?  Best CCC to use, best Stream SDK to use, and how to get them to interact with each other properly?

Mmmm, good point.  Might just be more economical to set up dual-card rigs then... PSU and motherboard both would be cheaper.  About $250 for a baseline two-card rig, and $400 for a baseline four-card rig.  Only saves $100, and might be more hassle with setup and maintenance.

Hmmmm, 5870's get 395MH/s?  And 5970's get 720MH/s?  Are you assuming overclocks?  Or is this page just completely wrong?  https://en.bitcoin.it/wiki/Mining_hardware_comparison

Also, I've searched and searched and searched... what exactly do the -f and -w switches do?

Because 1 5970 = roughly 550 MH/s, and 4 5850's = roughly 1000 MH/s.

Motherboards with 4 PCIe slots can be had for $140.  In fact, I priced out an entire base system (no video cards) capable of running 4 video cards at $397.  So about $1000 in hardware would be getting me 1000 MH/s.

Just curious what thoughts you all had on the best way to go about setting up an initial single computer farm, to later be expanded.  I am trying to keep initial investment costs down until the hardware has paid for itself, then continue expanding.  Looking to spend... oh, maybe $600 max?

Right now, I'm thinking AMD-based, with a good PSU, and a couple of 5850's.  Ram doesn't matter, and processor shouldn't matter (right?), so probably just whatever is cheapest that will run the computer on both those counts.  But is there a more recommended setup?

The reason I say 5850's is because they currently hold the crown for MH/s vs initial cost.  You get 250 MH/s for spending only $156.  They are also pretty good on the MH/s generated per kwh of electricity.  Not the best (the 6990's take that crown), but only about 20% worse than the best.

Obviously, the issue not taken into account there is that you can only fit so many cards onto a single motherboard, so that would increase the price/MH/s vs a higher end card, like a 6990, that could potentially run much more MH/s on a single motherboard.  I haven't really taken this into account yet, since the price of a "base" machine could vary a good deal even just from different PSU's for different sets of video cards.

Anyway, enough with the rambling.  What sort of setup should I go for with $600 to spend?

Oh, and also, how hard would it be to set this up on linux?  Especially for a complete linux n00b (I've installed it on a couple machines, and browsed the web, and that's about it).  Not having to purchase a license of Windows for every rig I start would also help keep costs down.
