Computer hardware used to depreciate just fine on it's own, but now with hardware being purchased specifically for bitcoin mining, you can actually watch it depreciate on a weekly basis!  ;D

it's certainly insane on many levels...

LOL

I dont see the draw for these...  2 5870's will give you the same/similar Mh for about 450 bucks

I'm thinking 6870's are the best buy at the moment. You can score them for $189 on sale and get ~300 Mhash/sec.

I have a feeling that if i purchases 6990s instead of other cards.. i would mine with them for a while and
just when I wanted to sell them 7xxx would come out and the high end gamers would have no interest in
them especially if they blow them out of the water for a certain price point.

the cost per mh/s just does not make sense to me. but perhaps a spread sheet analysis now days might show
a different trend.

btw.. out of stock. lol.

Sent you a gift thank you buddy.  8)

That didn't last very long...

BTW, thank you for you token of appreciation whoever you are! :)

Ah! it was you :) Thank you!

Out of stock, holy shit that was fast.

Edit: restocked.

Dual gpu on a single PCB cards do not have a good resale value. MOST gamers just get 2 or 3 cards. I had to sell my 5970 for just $300  before the bitcoin craze took off.

5830s retail for $109 (when they are in stock, which, they aren't right now) and can get easily get 280+ MH/s.  I'm actually selling a pair of brand new 5830s right now (never used, as I don't mine):

/shameless plug

Can someone explain to my why 6990's... from what I've read you can get about 700 mHash out of them which is no doubt a good rate but that's still $1.06 mHash, seems like there are cheaper options?

the idea is that you can fit more GPUs into 1 rig.  1 card = 2 GPUs as opposed to 1 card=1GPU.

That only makes sense if space is a premium cost. Otherwise, you could build a cheap mining hull for like $300 to slap another 3x video cards into.

5770's and the like are back in stock as well.

and that is exactly what people figured out.. and why 5830s were so darn popular. cheaper to stick in
two 5830s on a cheap machine then to buy a MB/PSU/etc that can support more cards/power.

6990s are not worth it. Period.

They are noisy too -- go ahead and google it. I was tempted to buy one used for $600 from someone locally, then I found out they A) run hot and B) run loud.

Oh, and they have a lousy $/MH.

Unless there is a motherboard/PSU drought where you live, skip the 6990.

check this out...  newegg removed the products from my cart after not visiting the cart for half hour or so

MSI R6990-4PD4GD5 has been removed from shopping cart due to quantity limitation/insufficient stock. Some combo items might be affected by this.

That's normal. Unless you hit "place order", the items aren't reserved for you.

Unfortunately, a virtual shopping cart does not equal a real shopping cart.  >:(

or just get 5830s which are widely available at around $160(no rebate/sale needed) and can also easily do 300 MH/s, or wait for newegg to get some in stock at $109

It's all noisy when your running as many fans/cards as I am. Are you saying that cause you can't afford them or are you being serious? You have a limited amount of space with all motherboards, so you have to determine what combination is going to give you the maximum MH/s, and at this point in time the 6990s that are what give you the maximum potential off a standard motherboard. If you're on a budget and just slowly trying to get into this then sure there are more affordable options. I think if you could modify a main board to have 10 wide angle pci express slots,then you could make the argument that it's better to go cheaper and duplicate. However, when you are working with a limited amount of space (most standard atx motherboards) you have to squeeze the most power you can into that space, to maximize potential, and productivity. Whats better, having 10 6950s and 2 different computers (mobo,cpu,ram,harddrive, and fans, not counting cases cause I know some people like to go ghetto.)Or having 4 6990s that do the same job with half the power, Whats more cost efficient with space,time,energy? It will look like your saving money in the beginning, but you'll end up regretting it in the end when difficulty goes up, and your sitting there wishing you went for the better investment.

10 6950 (ref models) can do 425 mh/s.. so that would be 4,250 mh/s.
4  6990s (any model) can do, lets say 800 mh/s so that is 3200 mh/s.

looks like we need to toss in two more 6990s to get over 4,250 mh/s solidly.

lets say the 6990s need 400 watts each. 6 x 400 = 2400
lets say the 6950s need 200 watts each. 10 x 200 = 2000

price of a 6990 is about 700? Sounds ok to me. 6 x 700 = 4200
price of a 6950 ref model is about 260 lets say. 10 x 260 = 2600

6990 at retail price just do not make sense at all to me. especially when ram and proc are dirt cheap.
mother boards might add some in cost but 750-1000 watt power supplies aint that expensive. HDs can
be had for dirt cheap too. so even adding that on in cost you will still have money left over.

now 6 - 6990s.. getting that all to fit and work on only two motherboards aint so tough but those power
supplies will kill you. You are not finding those under 100 bucks. etc..
