Topic: Is it still profitable to build a mining/gaming rig at this time? - page 2. (Read 2516 times)

Exactly. But When you're seeing the price fluctuate by $10-$20 a day on average...

But then we have the problem with the exchanges charging 0.6 % per transaction, which comes down to 1.2 % per trade.
Now that is all fine and good as long as the bitcoin is flying all over the place, as soon as it doesn't though...

I've been mining solidly for a week about now. I happened to have a 6870 already, without having any thought about mining.

I have made about .18 BTC and lived with a lot of noise and increased power. It was fun, but the way the market it is, I feel that I could make more money on an exchange...

I've been looking at it and it looks like BTC mining averages out to roughly 100MH/sec per $100-$150 spent.  It's not a bad investment until the ASICs hit the market and crush the GPU miners.

Litecoin mining seems to be about the same, 100KH/sec per $100-$150 spent.  It's not a bad investment until the ASICs hit the BTC market and all the GPU miners switch over to Litecoin mining and skyrocket the difficulty.

Both seem to have about a 3 month payoff period and its profit after that. 

So, basically your betting whether the ASICs will hit big time in the next three months or not.

If you think they will, you're better off just buying coins.

If you think they won't, go for mining.

If you're going to actually use the computer for gaming and mine during your non-gaming hours, then the mining is basically free and you should go for it.

Hope this helps!

Go to newegg or tiger direct they have most of what you are looking for. You can build a good rig for well under the two k. so build a great gaming rig and put a dedicated gpu on it as well then when you are mining you will have three gpu's to use.

One thing that is hard to put into equation is the future price of bitcoin.

I think a top-end, efficient GPU mining game PC is still worth it because I can see the price rising in the future.

However, invest for the sake of gaming, not for mining.

Where is Here?

Thanks for this reply. Any recommendations where I can buy? My town sells this at $536 per card for the sapphire one and $292.56 for the powercolor brand. I was hoping if I can get it cheaper at other stores [they dont offer bulk discount for either sapphire or powercolor; there are no other brands available too]

I would only recommend mining for those who are in it for the fun & learning.  If you're solely looking to profit, you'll likely go crazy with the large swings in BTC value lately.  If you're a geek like me though, you'll enjoy the challenge.   

I have a number (19) of Sapphire 7950s that have been doing well, and a few of the Gigabytes. GPU mining profitability will continue to sink with the SHA256-hashed coins due to ASIC I'm thinking, but we still have a lot of life in scrypt probably (e.g. Litecoin, Novacoin, Feathercoin).

THanks for this. Really helped me a lot.

Planning to buy 7950's, but regardless of brand, will a powercolor do better than MSI?

Solar Panel? lol you'd spend a fortune to get one big enough to use even if you lived in Phoenix AZ

Power Rates depend a lot on where you live in the world, I am currently paying .0803 kw/h + taxes

How do you figure? If you have a disposable value of $2k and bought 2 miniquads (just using as example since I was just looking at them there are better options) at 1.6GH your making on a broad guess of $483 a month. Even if it takes a few months for ROI.

if you have a mining rig hooked up to a solar panel and live near the equator...then yes?

borrow your neighbors >

if you have free electricity than you can use it to mine ltc profitably.

AMD 990 Motherboards brands is your choice, but my preference has always been ASUS or MSI

RAM depends on what you are planning to mine. BTC mining is just GPU dependent so it doesn't really need a good CPU or RAM, LTC mining uses your RAM and from what I have been reading requires about 8 GBs id spend a few bucks and buy some Corsair DDR3 1866 sticks, if for nothing else better resale

I have been getting 605 MH/s (BTC) and 640KH/s (LTC) using the MSI R7950 Twin Frozr at 65C @ 4500RPMs, MSI uses good quality parts and their cooling is very good ((see link in post above)) and also remember these suck about 250w of power each

if you are using 3 or 4 cards you will need to use PCI-e riser cables see http://www.cablesaurus.com/

I only use Corsair PSUs as I have had a great track record with them for myself and my customers, I build/repair systems as a business, plus I love the new i series PSUs being able to monitor the voltages live makes OC'ing a shit ton easier.

Another thing to consider is most PSUs are rated at 80%+ so if you have a 850w PSU that's only 80% certified its only going to give you 850*.8 = 680 under full load, so always check your PSUs rating, as once cheaper PSUs warm up their efficiency drops like a rock. So look for Gold or Platinum PSUs

Windows is easier in my opinion (i know windows well) but costs $100, where if you know Linux it can save you money

A lot of people like these cards http://www.newegg.com/Product/Product.aspx?Item=N82E16814127667&Tpk=R7950%20TF%203GD5%2fOC&IsVirtualParent=1

The MSI Afterburner software can unlock the voltage, core/memory speed to allow for about 500 Mh/s for BTC mining.  Power usage is low and you can get 2-4 of these setup in a single "rig" pretty easily.  Looks like they are out of stock right now but I wish you luck.

New

Honestly I would say its profitable if you can spend atleast $500. Getting 800 to 1.5GH will cover your electricity and generate profit. When the ASIC's come out thats a whole new ball game. But given the way all the ASIC's have been playing out recently it'll be a while until their presence has made an impact imo. Start now you'll come out on top, later on it'll just turn into a race to the first TH miner.

Edit: If your looking to build a top spec gaming pc. Why not go to newegg and sort by most expensive that coordinates with your budget? That seems to be the most viable solution.

Check the hardware at the bottom of this page https://bitclockers.com/calc if you're happy to decide what GPU to use, based *primarily* on mining.

Have fun! As you probably know GPU mining is in decline, but investing in BTC currency is another risk entirely. Either way, assume that you're relinquishing the cash, and be pleasantly surprised if/when you make a profit.
