Title: New card for mining Post by: txoomy on March 23, 2013, 01:56:02 PM I priced out a new card for mining.
$409 Radeon HD 7970 OC 3GB GDDR5 PCI-E w/DVI, HDMI Thoughts? Title: Re: New card for mining Post by: Aahzman on March 23, 2013, 02:00:39 PM Don't waste your money on GPU for mining. You'll get *maybe* 800MH/sec out of it, with a lot of tweaking, swearing and frustration. Order a $1300 60GH Avalon ASIC, and for the cost of 3 of those cards, you'll have almost 77x the hashing power. Or pre-order a pair of BFL Little Single ASIC @ 30MH each, for about the same price. You won't see them until probably June/July at the earliest, however.

I agree don't buy a GPU now but use what you already have ;D Title: Re: New card for mining Post by: txoomy on March 23, 2013, 02:18:04 PM Avalon batch 3 are 5000$ I agree don't buy a GPU now but use what you already have ;D I don't have anything yet.. I wast going to build a new PC with that card. The total build came to about $1200.

You won't see them until probably June/July at the earliest, however. I have a budget of about $1500 for a new PC, for just mining. I want to buy one this weekend, not wait til summer.

As somebody who built a new PC in January, mostly for gaming, but with an eye towards mining as well, the other posts in this thread are correct. You'll maybe get up to a BTC or less a month, currently. Which, if you're okay with that, go for it. But those aforementioned ASICs will be coming out en masse soon enough (unless butterflylabs is a complete scam after all), and when they hit the blockchain on a large scale, the difficulty will shoot through the roof and GPU mining will be increasingly not worthwhile, even with the BTC price so high.

Title: Re: New card for mining Post by: Gator-hex on March 23, 2013, 02:32:19 PM Get an old PC off ebay and stick some 5830s/5850s in it and you'll be gaming & mining for <$400 total.
Title: Re: New card for mining Post by: txoomy on March 23, 2013, 02:36:39 PM Thanks for the feedback. What are the different configs available with ASIC.
I want to control my budget.

But if I have a budget of $1500 for a new build, will going with a 7970 give me much better results? Title: Re: New card for mining Post by: Tejsei3 on March 23, 2013, 03:35:43 PM Recommend you do some calculations, such as MH/s/$ and MH/s/W for each of the cards.
You can find common MH/s, Power, and price numbers here: https://en.bitcoin.it/wiki/Mining_hardware_comparison Also, look at your electric bill and see how much you pay for power, for example, $0.16/kWh For example, say a 7970 can reliably do 650MH/s at 200W (not sure if this is right, check the numbers yourself) and goes for $400. MH/s/$ = 650 MH/s / $400 = 1.63 MH/s/$ MH/s/W = 650 MH/s / 200W = 3.25 MH/s/W Do the same for the other cards you're comparing and you'll have a basis for making your decision. This is a great application for a spreadsheet. I've done the same analysis myself and for quick payback you can't beat a $100 5850, but if you're looking beyond 6 months a 7950 is a great card, but at $300 it'll take longer to pay back. After the payback period you're getting much more hashing power for a given power requirement. The difficulty with all of this is no one knows what will happen. Will difficulty increase? How much? Will ASICs hit sooner or later? Will GPU miners migrate to Litecoin or just sell their hardware? How will the price of bitcoins and litecoins vary relative to your local currency? Lots of unknowns, that's why they call it gambling! Title: Re: New card for mining Post by: txoomy on March 23, 2013, 04:33:51 PM Thanks, great answer. I'll look have a look.
Title: Re: New card for mining Post by: JoroBo on March 23, 2013, 04:49:49 PM For now there are not many options for ASIC - Avalon are the only known company that actually managed to produce and ship them. Butterfly Labs is the other contender who are supposed to start shipping any time now but they initially had to ship their products in October or last year anyway...
