The margins on this hardware are non-existent, no matter the volume. Good luck with whatever you go forward with, but I would be willing to bet a few coins that it is a waste of time and effort.

You probably didn't bother to ask on the price on those 7 7950's did you? Bet it's over $350-400 bucks. If you order 100, if they were even available, I'd bet you'd save less than $10 ea.



Not so sure about that...the exact same vid cards I bought before Christmas have increased in price by 40% so someone is taking some cream.

With that being said, I am getting enough LTC to convert to 1BTC in about 6 weeks with 3 x R9 280X's.  $1500 of ASIC gear does about the same thing.

I am thinking that the reason a group buy may not work is because there is no motivation to sell these cards any cheaper...they are worth what they are worth.

$337 is what I was told. I stopped by today because I was going to buy them but she was already closed and Ill have to wait till Monday.
I cant imagine that a retail store would carry an item that they make a $10 mark up on when the product costs over $300 but Im not in the electronics business so I cant say for sure. When I have to pay out a vendor or use my credit at a distributor I expect to make at least 12% when dealing in wholesale. Especially if I have to house the products, once again I dont deal with electronics for a living I deal with shit (literally).

Also I was not trying to make a tun on this I am simply trying get some deals here and pass them along to the community. I do just fine at my day job this is just a hobby for me. Thats why I was trying to start small here and keep it simple so that it does not consume to much of my time. If that becomes the case then I will simply pass on the opportunity but I would still like to explore the option before giving up.

I'm pretty new to mining, but I have a few R9 290s that seem to be good bang for the buck miners if you can get them at a reasonable price.  The 290x is a bit faster thought so if we can get those it would give us the biggest bang per PCI slot.  The way to figure it is figure how much hashing power you expect per dollar on the card with a slight weighting toward the higher power cards because you can only get so many in each PC.  So with lower power cards you cost per killahash goes up due to the need for more PCs and thus more electricity to run them.  My head hurts too much to do the math at the moment, but it's really all about the price of the card.  Whatever card gives the most bang for the buck is the one I'm sure we could all agree on.

I'm currently running 3 290xs, 2 290s I got on deals, a 7970 I got on a deal, and my 3 old 6970s and a5870. I'll have to add another mining PC if I add many more cards, ?I already have to run a heavy duty power cord to the bedroom I keep my miners in because I blow the breaker if I don't. The Sapphire Tri-X 290Xs are outstanding because they have an excellent cooler on them that is fairly quiet. (It stays about 20 degrees cooler than my other 290x without much noise at all)  They are great if you mine on your main working PC since you can stand to be in the same room with them.  They also overclock well, but I've found that you don't always get more hashing by raising the clock, sometimes you get less, seems you have to find the right combo of GPU clock and Memory clock, but I'm still experimenting there.  I just got the cards earlier this week. They are very long though and won't fit in older cases, but since most of us will have to run on risers to get any air to them that isn't a huge deal.  The reference design coolers on the 290s suck.  The temps are always near 95c and they sound like a hair dryer.  Happily I have those in my basement that I hardly ever go down to.    Grin

I've read that the 280xs are good bang for the buck miners too, but I don't have one of those yet.

Anyone in the mood to get in touch and check if any of these listings are legit http://www.alibaba.com/products/F0/radeon_7990.html seems too good to be true but who knows.

Everything I have read here on this forum has shown it to be about 50/50 for legit and scam.
People seem happy with the buyer protection but it can be slow to recover their money.
Also a big chunk of advice is to check the sellers feedback and such.
It does look too good to be true but not sure.

The 7990 would be the best card to get until they come out with a dual chip R9 290x...  But I haven't seen any anywhere but eBay and a few small e-tailers and at insane prices every time I looked.  The Ali Baba link looks sketchy at best.  Only non-reversible payments and no feedback or Ali Baba site inspection.  Have you tried contacting them to get a price? 

I contacted one of them with this message:
"Hi,


I'm interested in buying several Radeon 7990 video cards and am in contact with many other people that would be interested in buying several more each.  I don't have a full count on quantity yet but would be surprised if it's less than 30 if the price is right and would be very interested in getting your price quotes and brands you are offering.  If you have different price points for different quantities please give me a list and we'll try to get as many orders as possible.  Also interested in what kind of payment terms you will accept.  Many of the people involved have been scammed out of money buying items that never shipped so we are an understandably nervous bunch and would need some way of secure payment, possibly an escrow service or American Express card payment to assure that we are not sending our hard earned money out without the guarantee that we will get what we ordered.  "

We'll see what happens.

Nice one man, do let us all know what they reply. If they're legit perhaps we can organize a group buy for those beasts.

I'd be interested in buying many 270Xs , if they are the right price (less than 200$) and delivered to UAE .
i have access to electricity as cheap as 1.5cents/kwh , and i have over 300 amps of 220V .
we've already bought 50x 290 + 60 7950 , i guess 270 is a good bang for the buck !.

Note, scrypt ASIC in initial $/KHs investment moved very close to GPUs. Given much lower Watt/KHs ASIC is about to kill GPUs.

270 (non-X) = $180 = 490 kh/s = 2.72 kh/s per dollar
7950 = $300 = 750 kh/s = 2.5 kh/s per dollar

Of course, you'd need more of the 270s to get the same overall hashrate than the 7950s; more risers, more motherboards. Also don't forget about power consumption, additional PSUs.

The 270s run nicely on 5 or 6 card rigs on only 1 1000~1050 watt PSU.
