Depending on how desperate they are to get it you could force them to pay the shipping

Anything above 900 watts is extreme overkill if you go with a good brand.

Yea I can only imagine the price lol. That and the total wattage used I believe is around 330 for each so 7x330=~2,300 watts so like I said earlier it isn't really cost effective because you'll need multiple super expensive psu's.

I think I remember hearing about a single slot 6990 but with a card like that it doesn't really matter if its single slot because you cant really fit more then 4 cards (cost effectively) into one case anyway.

I agree basically with everything thats being said.
I have heard this corsair 750 watt is amazing.

If you don't get something like this bump it up to 900ish and you'll be fine.

I am including the mir but there are multiple cards at 155 with a mir.

edit: I'd also like to point out a 6870 is slightly better that a 5850 on power consumption. I feel like thats negligible though.

You were holding the link hostage you weren't asking for donations you wanted to be paid. I also feel like you had no intention of giving up that link for free or you'd have lost your bargaining chip.
Again a donation is paying some one for something thats free not paying first then receiving a service. Also it's shady because lets be honest you have to pay for a link that most likely wont work for you. Regardless of the fact that you may or may not have refunded them. They paid for a service that wouldn't work for them because you weren't honest that it was a Canada only site.
To be fair the dude might have gotten carried away lol
No one said the deal wouldn't work but it is a Canadian site. Did you expect the majority of people to be able to use it? As to clicking the link part I have no clue what your talking about I actually checked to see if it had shipping to the US.


Regardless of my view of asking for donations(which I think is pathetic unless your releasing major software that took 8-10+ hours to make) you weren't asking for a donation.

I quoted the 6870 not 6850. Those are both the extremes of the card so its not like I wasn't equal to both cards. In the best case scenario thats the ratio you should expect from each and it should follow a similar pattern as you clock the cards less and less.

Can you cite this? I remember seeing multiple times people saying linux can hold more. This is one of those times.

Each card individually wont overheat if you control the clocks. It will overheat when the room temp reaches a certain point or if the cards are too close together. For all the rigs I'm separating them with risers and some I even used this example. http://forum.bitcoin.org/index.php?topic=29729.0

I assume you could have one of these machines with minimal to no ac. If you were to mass produce something like this you'd probably need 24 7 ac in the summer.

:s 209 isn't worth it. Thats just too high. A 6870 can produce 330 megahash for the cost of 155(http://www.newegg.com/Product/Product.aspx?Item=N82E16814102948)

409/209=1.95
330/155=2.12

A 6870 is by no means a good card at its current price and it still beat this 5850.

Yea when I first got into mining I tried cpu mining and my i7-960 was only producing around 8-9 megahash.

Its 8 on windows. I'm pretty sure on linux its a bit higher.

No clue what hashing speeds would be but I assume it would be inefficient at the brand new price point. What will really be interesting is the price drop in the earlier series and what new opportunities we might have with currently inefficient cards.

rebate is one per household most likely.

The 1x is less then a dollar difference in price so it doesn't really change things.

Edit: The site I'm about to post doesn't list prices at least that I see but take a look at this.

lol I admit you got me excited I decided to test a theoretical build implementing it.

Have a friend in canada ship them to you. A reputable canadian on this board might be willing to buy this for you and make you pay the shipping and maybe a 5% fee. That would still probably make it cheaper then the ncixus one.

Yea I'm not sure if if the splitter would work and I'm just trying to be creative and get people to stop thinking so narrowly that the 5830 and the 5850 are the only option. There are builds out there that make other cards just as competitive.
