I am curious myself with the Graphics Core Next architecture how that will affect hashing/wattage.

Most important for litecoin would probably be the 512-bit memory bus on the 290X.

I'm pretty sure that it will reach 1Mh/s, but look at the $649 launch price!
Hoping that rich gamers start dumping their 7950's and 7970's for peanuts

Probably around 25% to 50% more hash power then a 7970. So, probably around 875 to 1000 kh/s with the hardware specs of the 512-bit mem bus and 2816 SPU's....It should be probably use the same wattage as a 7970 or in between a 7970 and 7950....This is just my guess on it, so don't go by it 100%....

No it wont, compute unit of GNC2 i weak!
The 7990 is a dual GPU card and I've seen all comparisons online for the new R9 with the GTX Titan which is also a single GPU card... And I got all excited about this new R9 290X... What is the current best AMD based card for mining Scrypt? I know the 7950 and 7970 but you need quite a few of them to have a meaningful hashrate. I would try a 7990, has anyone had experience with it? My Asus Ares 2 was a monster card but I pushed it so hard that it died on me after a month... RIP. The reason is that I rather have less cards but more powerful so that I also need less motherboards, cpu's, PSUs, etc. Indeed, density matters. From what I've seen around the forum, the 7990's are very hard to cool. Make sure you undervolt and use PCI-e powered raisers

It's does save on space, but the heat issue and the crossfire issues make it not as good as the 7950 or 7970 in crossfire. Plus the 7950 has the best watt/hash rate.

What really matters and makes the 7990 unfavorable is that it costs $600 vs $450 of 2 7950's, not that one costs 3 cents more per kW/h than another

Thanks for the info guys, I'm keen on the 7990, the price has gone down considerably since release when it was bundled with 8 games. But will look into the 7970 too. What is the nominal speed of a 7970, 600 KH/s?

Around 600~700 kh/s, mileage and oc'ing varies per card. But the 7950's a per watt/hash rate king then the 7970's and 7990's. The 7990's is a more convenient package of packing two 7970's in it though at $600 on newegg for one, I'm think about getting one, maybe...

I will skip until someone confirm it is voltage unlocked Depends how energy efficient the new card is, that voltage unlocking might not be required. As with CPU's, GPU's can benefit with die shrinkage and energy savings with higher performance too...

I would be really happy if the energy efficient increases. But on the other hand I am worry that FPGA for scrypt is coming to the market

But on the other hand I am worry that FPGA for scrypt is coming to the market I live in California, I'm paying $0.1323/kwh....FPGA to scrypt could happen, more likely then ASIC, as you can make an FPGA be more memory intensive like a GPU card...But that's still a maybe for FPGA miner for scrypt....

I am also waiting to get my hands on one of these to test. They should be here within the next weeks so we will know soon enough. But with some retailers slashing prices on 7950 cards now, I think this is the better deal.

I could be mistaken though. I will be glad to start mining with real cards again. These non reference designs are crap.

Base on my understand, most reference cards are locked, of course it also depends on the brand.

Until the 7900 series no one wanted non reference.
