I was really excited about this since I could use 100 btc but if I understand the rules correctly this is the dumbest contest I've ever heard of. Basically you are giving the person with the most btc 100 more btc. Due to bitcoins nature a rich person could generate hundreds of addresses and vote for themself and it would look like different people.
That's the way I understood it as well. I'm still a "maybe" on this, but it sounds like fun.

Good response, edd. Here's hoping that Mousepotato accepts the challenge seeing that it's not a trap while she reaches for the cheese (100 BTC grand prize--winner take all).
~Bruno~ I might be down for this. But keep in mind I work full time and go to school too, so contest tasks will have to take a back seat to my IRL priorities. As long as the tasks don't involve going out into the woods and surviving on bugs for a weekend Also, while I can do video presentations, I'm horrible at public speaking, even if it is into a webcam. How many contestants are there so far?

What's funny to me about all this is that gpu mining the coin early before anyone else could is exactly what coinhunter did with SC . Such a douche. You should be banned from this forum. Well.. yeah, SC started out as a GPU chain.

At least ArtForz was mistaken about Cell earlier Just let's do some simple math. Playstation3 has 6 SPE cores, each clocked at 3.2GHz and 25GB/s of total memory bandwidth. Calculating one hash needs approximately 434176 ADD/ROL/XOR operations on 128-bit vectors in the performance critical part of salsa20/8 which are executed in the even pipe (shuffles and the other instructions are executed in the odd pipe). Also calculating one hash needs 256KB of memory bandwidth (128KB is written sequentially, 128KB is read in scattered 128-byte chunks). So taking into account that SPE core can execute one instruction from the even pipe each cycle, the theoretical performance limit based on computational power is (6 * 3200000000) / 434176 ~= 44.2 khash/s. The theoretical performance limit based on memory bandwidth is 25GB / 256KB ~= 95.4 khash/s. There is a lot of headroom for the memory bandwidth and arithmetic calculations are the bottleneck. Though Cell has precise control over memory operations by scheduling DMA transfers and can overlap DMA transfers with calculations. This allows to utilize memory bandwidth very efficiently for scrypt algorithm. This page seems to say that HD 6990 has 350GB/s of memory bandwidth. And here ArtForz tells us that it is possible to achieve < 20% peak BW with GPU. Doing some math again, we get 350GB * 0.2 / 256KB ~= 267 khash/s. Looks rather believable to me. Check out the big brain on Brett!

At 250 kH/s with your 6990 your daily yield is right around 160 LTC at current difficulty (estimating with http://www.litecoinpool.org/stats, and ignoring pool fees of course). At an exchange rate of .002802 BTC per LTC that means you can exchange your daily take of LTC for roughly .44 BTC. Now if you were mining straight BTC with that 6990, you'd be doing around 820 MH/s which yields around .60 BTC per day, maybe a little more. I'm guessing that you'd need that GPU Litecoin miner to hit around 350 kH/s or so before you start breaking even versus mining straight BTC.

I don't understand why you'd waste valuable GPU bandwidth to mine Litecoins, if Bitcoins yield more profit.

Oh and i have made some dozens of full custom chips at 28nm specifically tailored to mine bitcoin and litecoins. 1 terahash per chip. True story.
Ships in 4-6 weeks?

EXIF data is about as accurate and reliable as the files date/time stamp.

$210 isn't such a hot deal though. That's what they were going for back during the peak last year.

If you bought four 7970s and still can't maintain a 1.00 KDR in BF3/MW3, you might be a miner.

Using Catalyst 11.11 on a headless Win7 box (Absolutely nothing connected to any of the video adapters)
Phoenix 1.7.3.
cmdline: phoenix -u <localproxy> -k phatk BFI_INT FASTLOOP=false AGGRESSION=7 DEVICE=n WORKSIZE=128 VECTORS Thanks! I'll have to upgrade my Phoenix later. I think I'm still on 1.50. Are you using whatever SDK came with 11.11? I remember there being some issues with CPU load with that driver IIRC. Sorry for veering off-topic.

Wow, Jizz that's nuts. Would you mind sharing your Phoenix command line options? What driver+SDK version are you using?

It is a great deal for a gamer.
They had 106 in stock yesterday...100 today.
Hey.. how do you tell how many they have in stock... I can see the little percentage bar, but how does that translate into exactly how many in stock? thanks, Sigg Input a really high number of cards (like 100 or 120 or something) and keep decreasing the number until it actually shows up in your shopping cart. If you put in 97 right now, nothing will show up in your cart. But if you input 96, it will. Thus they have 96 cards as of this post... at least I'm guessing that's how it works.

Where does CosbyCoin fit into that list?

You guys should try reading the works of Jeff K over at SomethingAwful.

Perhaps something a little more Cosmo in your approach?
"Desperately seeking BitSusan?"
"Tech-savvy SWNM seeks fun-loving, hashmate with benefits?"
I like this, but what does SWNM mean?

I think there's a gap in your poll options. What about fan speeds of 61-69%?
|
|

That's still probably one of the best bang for your buck for gaming though.

188 vs 228 I believe. The 2GB version takes an 8 pin and a 6 pin.
The price is still too high. Hopefully no one buys them and they dump them <$150.
If that's accurate, then wow. 228W is encroaching on 5970 territory, but at half the MH/s.
