It's interesting when I saw those trades yesterday I was thinking "Man someone got a great deal buying at $8 when the market price is $22+"
It's great to see that Tradehill found and is able to solve this problem quickly.  I just signed up for an account with Tradehill a few days ago, made quite a few trades, and so far it's been excellent.  Keep up the good work!

Bump, Amazon canceled all the backorders of the Sapphire 6990s

You can always hedge by selling a percentage of your holdings.  If it goes down, buy back in!

they want you to spend more money and buy the 6970

Put your numbers in.  You can change the difficulty factor and take guesses at the exchange rate.
1 month numbers are not accurate since the difficulty would have adjusted a few times in 30 days.

Hashing power will plateau, especially when ATI is having problems keeping up with demand.  When the 5830/5850 are gone, people will look to higher end cards that are still in stock like the 6950 and 6970.  It will just get more and more expensive to get into mining and expand the farm if the decent video cards are out of stock.  (One will need to spend more $ to get 1 Mhash than before)

This might be a good thing, slow down the hashing power, for a chance to catch some breath.

Even with extender cables, I would like to see you fit 8 cards on that thing without having the motherboard melt

ok let us know how that works out, are you a troll?

go look at this chart:

Add up the Mhashes add the other equipment like motherboard, memory, power supply, see what fits your budget.
Check to see if the cards are in stock first

a few weeks dated but it's a good start:

The recommended video cards are hard to find now

Anyone know when retailers are getting these back in stock?  I placed an order on Amazon a few weeks ago (Sapphire), and the estimate is June 20 to July 7th.  I noticed at the time, new orders were given an estimate of "1 to 2 months" and currently that has been changed to "Currently unavailable. We don't know when or if this item will be back in stock."
So have you checked back with your retailer lately to see when these are coming back?

UPDATE June 10th:
Amazon canceled all my backordered Sapphire 6990s.  Here's their email:



"Hello,

Due to a lack of availability from our suppliers, we will not be able to obtain the following item(s) from your order:

   "Sapphire Radeon HD 6990 4GB DDR5 DVI-I/QUAD MINI DP PCI-Express Graphics Card 100310SR"
  http://www.amazon.com/gp/product/B004R1Q4VW

We've cancelled the item(s) and apologize for the inconvenience."

If you don't blow up your laptop, you will probably greatly reduce the laptop's life due to heat

senators can't even distinguish the difference between bitcoin and silk road

So they really didn't have any stock to begin with, or they sold 449 cards in less than 24 hours

nextdaypc stock still stuck at 449, anyone put an order in?

I am not sure that stock number is accurate, especially since you said the number hasn't gone down since you told everyone about it.
Maybe someone can order a bunch and report back.


Here's a review recently from resellerratings about the accuracy of stock numbers:

"posted May-31-2011

Absolute WORST Company. Parts were not on stock even though the website said 30 available, and continue to say 30 available. Customer service reps were rude..."

I'm talking about the major US retailers: Amazon, Newegg, etc...
Sapphire 5830s are all gone.

5830s are out at the major retailers, I think the next to go soon is the 6950s followed by the 6970s.  6990s will be coming back in stock in a few weeks, but they will probably be swooped up very quickly.  If you're out of plugs in your house, maybe you can go into the video card hoarding/resell business after all the good cards dry up?

Gotta check up on the status of the rigs.  Can't let a computer sit idle due to power failure, computer crash, tripping circuit breaker, etc..

I think that's a total coincidence.  The 5830 has been recommended in the Wiki Mining Rig page for weeks:

It's also the cheapest card to buy to get into the game with little investment.  I think that's the reason why it sold out, not because of your chart.
