How did you figure this out? No computer of today could generate that without use of GPUs.

Yeah I'm using a GPU miner, it took me around 30 mins to setup but it basically was just a program to download and run.

I'm getting 180 Mhash/s

Nice, what GPU are you using and did you build the PC yourself? You can build a PC for around $1000 using 4 GPUs to pull around 1K+ mhash/s

TC, just to sort of merge this discussion, I would do this mostly as a warm-up to a potential larger project.

Assume $30 BTC in 12 months
Assume 75% hardware depreciation in 12 months
Assume difficulty increases 200k per increase for next 3 months, then 5% after that.
10c/kWh

96% uptime, 2% pool fees, etc. Selling every day, a $700 rig would generate over $700 in profit the first year ($1,100 if not for trading fees). The real risk is a decline in bitcoins, but even then it beats owning bitcoins. The other risk is if it goes up ~250% or more this year then you'd have made more owning coins.

Note: those difficulty figures are very solid, imo, for the price scenario presented. I think we'll see about 200k increases as the miners rush to equilibrium and then after that difficulty and price should increase on a roughly 1-1 basis.

I got an XFX ATI Radeon HD 5770, the card cost me only £70 brand new, and over clocked I can get 190 Mhash/s @ 80c, I can't get it stable yet though. It seems like a nice card!

The 5870 can do 350mhash/s though and is less than 50% cost, so two of those seems the best way to go, am strongly considering ordering 2 of them tommorow but will mean I have to buy a new mobo with 2xPCIE slots.

I'm mining with about 1.3GH/s right now, and adding another 1.2GH or so in the next week.

I can answer mining questions if you guys have them.

Icy's deal is not good, if there was any doubt about that. It's not hard to build a machine or set up mining on it, which is why mining has exploded in the last few months.

If you could answer some questions that would be great, seriously considering buying a rig tommorow, can you list your exact setup, and at current market rates what's your earnings per day? (don't deduct costs).

I'm considering 2x5870, that should do ~800mhash right?

Your right its only not good if you know how to do all of that (or want to do all of that), a lot of people wouldn't know how to start and A LOT of people don't know how to even build a computer that would get the most out of computing for this network without high cost.

Any computer you buy with good graphics cards will have a lot of crap you don't need, making you waste money into stuff that won't be used.

how many bitcoins can you guarantee for a 1000$ investment?

Its no guarantee, I can only guarantee any profits made every month until bitcoin fails for some reason, or the computer burns out, which wouldn't be for at least a year. (it will take around 2 months at the current rate to make back your money)

Again, if bitcoin should fail or become unprofitable, the hardware can be resold for 75%+ of its value.

this is a joke, right?
many of the guys ITT are agreeing that with the current growth of difficulty, you will earn less coins with rigbuilding/mining than just buying them on mt.gox now.

and you want to take away a 40% cut of that? thats ridiculous.

Most investment deals don't even give you 25% of return, with this deal your getting well over that.

Your ITT guys are idiots then, Bitcoins fails if running rigs are unprofitable because they are needed to support the system. They also apparently didn't take account for the price of Bitcoins have been going up with the difficulty level, and difficulty level can go down which has happened.

Don't come in here all high and mighty without doing some research.

The thing is, you can make a calculation about mining being "profitable", be wrong, but the correct decision is to "keep mining" since your sunk costs are sunk and your costs of mining are relatively small. Once you have the equipment, mining is almost always the correct play (assuming you have anywhere close to a power efficient rig and reasonably cheap electricity). So there can be a time when it makes sense to keep running existing rigs, but to not build any more rigs. You'll never be able to recover your investment (say difficulty goes up a lot or price goes down), but it still would make sense to try to recoup some of it.

LOL @ this guy.

40% return for tech support on buying a mining rig?

If you want to get ripped off buying a mining rig, at least go with a more cost effective way:

Tech support? Clearly your stupid.

If you are looking for people to rip off, just stick to the Bitcoin forums.

There are droolers who actually gave this guy money:
http://forum.bitcoin.org/index.php?topic=5750.0

That kind of crap won't fly here.

actually, the future price doesnt infulence the decision of buying vs. mining.

if you buy a 1000$ rig today and let it mine one million years, with a difficulty increase of 37% every 10 days, you will never earn 50 bitcoins.

Sure. I didn't want to purchase a complete dedicated system for mining, so I decided to use spare parts and purchase what I needed

Main computer - took out 5770 and replaced with 5870 - 400MH/s
Media server - added sapphire 5830 - 300MH/s
Dedicated miner
-Asus P5W DH Deluxe w/ e6600 proc & 2GB memory (was my old HTPC)
-2x Sapphire 5830
-Corsair 620W modular PSU
-Overclock with MSI Afterburner to 990/330 on each card. Set to start Afterburner with windows and start OC on startup
-Running win7 off HDD
-Phoenix with PhatK = ~307MH/s
-Dummy plug on each GPU
-Wifi module installed
-disable any halt on post error, enabled restore state on power loss
-auto-login user, put shortcut to both batch files in Startup
-logmein for remote admin. Could use vnc/teamviewer/etc, just has to be console view NOT TS (like RDP)
-Requires only a power plug to run and automatically starts mining

Total hash rate: 1300MH/s
At current difficulty that is about 2.26BTC/day (calc is down so I can't remember exact rate)
Mining primarily on Slush's pool (mining.bitcoin.cz) so 2% for fees. Backup is BTCGuild. Most major pools are getting DDOSed right now. fun fun

I haven't been selling yet but 2.20BTC/day at current rate is $43.78/day currently. I sold a bunch at $30.5 and waiting until it's over $25 before I sell more.

I have another 5870 and my 5770 that I'm going to put in another system, which is a DFI Lanparty Ultra-D MB. Also have 3x more Sapphire 5830 on the way from Newegg.

I've got an 850W corsair PSU that is going to run that and I have PCI-E extension cables on the way. Going to try to run 5870 & 2x 5830 (1 off extension cable) on this system, then probably put the other 5830 in my media server with another extension cable

Clearly most of you don't realize not everyone has the knowledge or the will to want to do any of this. Lots of people rather sit on their ass doing nothing.

When your making at least a 200%+ return, thats huge.

WOW! your an idiot. Do more research.

Most people don't have the knowledge to buy a rig, plug it in, and start mining?

Why would anyone take on all of the risk so you could get money for nothing?

But try the Bitcoin Stock Exchange, there are enough people dumb enough to give you 50 bitcoins to "invest" in your company.

You really think people have common knowledge of building a PC and programming the settings to start mining?

No, most people have knowledge to click on a link and follow purchase instructions, though.

lol? That has nothing to do with the building of a computer and the knowledge of what you need to make the most out of mining + the knowledge of getting everything setup.

I wish people would think before speaking.

increase: 37% every 10 days.
0.9 gigahashes
total generated coins: less than 50.




maybe i'm an idiot... but you are clearly at least 37% more idiotic than i am.
