Just built, 2 rigs, each has 6 7950 gpus and a MSI Z77A-GD65 mobo. 4 gb RAM. 32 gig ssd's. 1600 watt msi psu's.

Secured in a custom aluminum frame.

2 new Windows 8 discs.

$8000 firm for the lot.

Accepting btc or usd.

Will do almost 8000KHS overclocked.

Thats a looot of money, the new R9 280x - Costs 2500USD and the rest of the hardware aint expensive so come with a decent price

I'd offer around half that.

You can't find 7950's right now, and if you can they are over $500 bucks a piece.

Read the reply. R9 270x are the same card.

You are dead wrong on that, not even close. The 270x is identical to a 7870 and will only hash around 400kh...while the 280x is based off a 7970. There is no direct replacement for the 7950 in the R9 series. Go back to school and do you homework!

Was a typo as . 280X it was suppose to say. And please stop being a smart ass. im telling the man the 8grand is way off.

Do you accept escrow?

I don't know.  There are a lot of left over 7950's (used) that were being used to mine Bitcoins as recently as a few months ago.  I bought mine for about $200.

Yes

Please post pic of the rig when you have a chance. What processor did you use in these rigs ?

(2) Intel Celeron G1610 2.60GHz LGA 1155

I'll offer $125 for the GPU's. The other hardware is overkill and the whole system is overpriced.

Not intending to thread hijack here, but if this actually is the case I've got a Sapphire 7950 3GB DDR5 975mhz core 1300mhz memclock card that I'd be willing to sell. Especially if the price is in that sort of range  :)

The card is still under warranty, was purchased in march 2013 has mined, but never continuously for long periods, has also never been overclock and never ran hotter than 69*C

The 79xx series has been discontinued, and the supplies went dry, so yes it's true you can hardly find them.. but people are panic buying these cards when they don't need to. The R9 280X series is a rebadged/better 7970 going for $300msrp right now.

MSI 7950's (the best of the 7950) were going for $200ish until they went dry. No need for people to pay crazy prices for these right now.

Can you find me 12 in stock R9 280's? Looks like your best bet for those will be early January. Wonder what the difficulty will be then.

Meh, 7950's (280x's) are out there, not cheap, but not as expensive as you have them.

Uh yeah actually, there were 20+ of them over the weekend on Amazon.

Were.

Waiting on the next preorder email now. If yours were unopened, still in the plastic wrap, maybe you could get a slight premium. But definitely not opened.

Would you consider selling off two of the cards??
thanks

that made me look up my 7990 holy crap I paid $600 its selling for up to $1400.

Yeah it's nuts.. especially for used GPUs where there's usually no warranty left and you have no idea how much time is left on the card

I can:

Where in the world can you get a 20% off coupon??? That's like.. worth more than it's weight in gold(coin)!  ;)

Just ordered some of the higher end Gigabyte R9 280X's from Amazon. Might have ordered them out actually lol.

So yeah, you can find deals. Just have to keep on top of it. MSI is sold out entirely (at the factory level I heard), they're ramping up production for January.

gc4btc.com  I usually have it set on a 10 second timer to buy everything available so you have about 9 seconds to buy!

BUMP for the OP I didn't mean to hijack your thread.

Those are used... who knows how many hours.

And aren't XFX cards typically worse for Scrpyt than most other brands? I'm mostly just amazed to see 7950s selling for more than 7970s!

XFX is one of the least popular brands for scrypt for many reasons. Regarding 7950 price, it's probably because they were the most efficient workhorse at the time, and so people getting into the game late are like "omgz i need 7950s"

Outside of the 7990, I think the 7950 is still the most efficient.  But the prices on thosae are just as ridiculous.

Have you,sold them yet?

Im pretty interested if you still have this not worth 8000$ but im offering about 5000$ lmk

R9 270 & 270X are among the most efficient KW/KH ratio. 5 = 2.4mh @ 950w.

Suggested brands: PowerColor, Visiontek, Gigabyte, MSI

Also interested but definitely no where near asking price.

Speaking from experience, XFX cards run super hot for 2 reasons:
-poor cooling design, heat blows in all directions, onto the motherboard and other cards
-most importantly they draw A LOT of power!!  One card that I have draws over 30 amps (360 watts) at I 20 E 1075 M 1250 710 GH/s...I can only get decent hashrate in the winter outside in the garage on this rig.  When spring comes, it's water cooling and radiator time.

BIOS MUST be edited to undervolt these cards, they are locked.  So there goes your warranty.  All that said, I'm not afraid of using these cards, but these things have to be factored into the sale price.  Seller should show power consumption at receptacle to buyer before sale.

was wondering if you can send me the parameters to get 6 cards up to 4mh/s. I currently have 6 xfx 7950 and want them to be at 4mh/s

So is this still at that price or what? Or possible parting out? per price on GPU`s.
