this makes no sense. "by the time most people have them they won't hash any better than GPU -- relatively to the difficulty that GPU faces now compare to what ASIC will have to face, peoples predict a rise of 100X of the difficulty before all ordered asics are delivered".
Well then would this not render GPU's completely obsolete then? That would mean that GPUs would be WORTHLESS for mining if the difficulty increases x100

this makes no sense. "by the time most people have them they won't hash any better than GPU". there is absolutely no logic to this statement.
and the statement "ASIC prices are so high... " is FALSE because they are EXTREMELY LOW!!! For 25Gh/s for cheaper than a system with 2 graphics cards that does only 1Gh/s, is EXTREMELY CHEAP.

Re: Help/Advice for optimizing 2x Sapphire 7950 3GB
I am presently running both with all 7 boxes checked and no flags. No flags because I am using the computer.
First one stays at 415.8 Mh/s (occasionally increases ~1Mh/s), second one is the same almost all the time and only varies ~5 Mh/s, probably because that's the one my monitor is connected to.
Is this a good rate? Or should it be a lot better? What can I do to optimize it?
More details:
Software:
Windows 7 Ultimate x64 (Custom Slim & Fast Version)
GUIMiner v2012-12-03
Primary Hardware:
GPU: Sapphire HD 7950 3GB GDDR5 x2
CPU: Intel Core i7-3770K
PSU: CORSAIR CMPSU-750TX 750W
RAM: Patriot Viper 3 16GB 1866Mhz
Cooling: STOCK (room temp: ~60°F/15°C)
Other factors:
Daily use PC
Running GPU fan on 100%
Intend to run 24/7 simultaneously
GPU temp remains stable between 63° and 66°C
When I increased the GPU clock to 1050, it increased to over 500Mhash/s Combined total is remaining stable between 1.005 and 1.015 Ghash/s
Keeping the window open in my closet where my PC is, and fans on 100%, GPU temp for both so far are stable at 69°C. Room temp is probably around ~60°F/15°C.
Notes:
Additionally, using the flags -v -w 128 increases 20 to 30 Mhash/s (without the flags it's a combined total of about 985Mh/s). But with those flags you can't be also using the computer or it will crash.
Using latest version of GUIMiner
I attempted to raise clock to 1070, but shortly after doing so it froze GUIMiner and said "display driver successfully recovered from error." I assume it "recovered" by freezing GUIMiner.
Cards are in crossfire mode, although each is running individually in GUIMiner. This is because for some reason the latest CCC will only allow me to individually modify Graphics Overdrive for each card if it is in crossfire mode. If I take it out of crossfire mode then it only shows the Graphics Overdrive options for one of the cards.
Increasing Memory Clock does not affect performance in GUIMiner. Thus I kept the Memory clock at stock speeds (1250).

If we agree that the definition of doesn't exist means that they have not shipped a single one to a customer (except one unit to a developer to help finish their software - but that's a whole different can of worms), then yes, it doesn't exist.
Whether they will exist is a topic hotly under debate.
But neither of that really matters, because the fact is, if you order one and if it ships, you will probably not see it until the end of this year since there are thousands ahead of you since they began pre-orders last year. By then, difficulty will be sky high and the prospects of a reasonable ROI is slim to none.
What if i stuck into their facility after buying one and took one and snuck out?

I just found the disclaimer at the bottom of the pages:
Quote
Pre-order Terms: Bitforce SC (ASIC) products are in final stage development with initial shipping scheduled for the last half of April 2013. Products are shipped according to placement in the order queue, and delivery may take 2 months or more after order. All sales are final.
Can anyone tell me if this has changed? Like did it say "March" last month and "February" the month before? because in two days we will have reached the "last half of April 2013".
