Consumer rebadges of old cards (77xx, 78xx) based on the 6000-series VLIW4 arch. coming out first, new 79xx series cards based on totally new architecture coming out Q4'11 or Q1'12.
Also a 7990 "New Zealand" dual gpu coming spring next year. 28nm process and later shrink to 22 or 20 which means less power consumption, potentially smaller cards, more performance per dollar.
Any word on number of Stream Prox?

i don't know how you manage to find all this info on him, but thank you. i'll try to use this to maybe call his local authorities. so far there has been 9 people that said they have been scammed by this guy. if you also have been scammed by him and do not wish it to be public, then please PM me instead. any of you got your money back yet? who paid through dwolla? i requested his dwolla account to be locked, but dwolla declined that request until another person filed a dispute against him on dwolla. i'm not sure who that person was, but his account is now suspended, so if you paid through dwolla, please file a dispute. i think even if you paid with BTC, try to file a dispute through dwolla anyways because he converted that BTC to dollars and moved it into dwolla. if he scammed you by BTC, you MIGHT be able to get your money back, but in dollars instead of BTC, so try to file a dispute anyways. This guy moves around a lot. Info I'm getting from searching has him in Rome, GA. Gimme a few mins and I can probably find a phone # for you.

Turn on 2-step verification. So even if you have a keylogger on your system, it wouldn't matter. But then again your Email account would probably be the last of your worries if you had a logger.

The dollar is fine, it might have a slight cold but not even the flu, the death of the dollar has been exaggerated.
If bitcoin replaced the worlds currency, a lot of people would be screwed as they have no computers, though we an print bitcoins, it would take time to go over.
there is over 4 trillion dollars in circulation there are 6842600 bitcoins, so each coin would be would be worth $580,000. Which means miners would find about 1.2billion every week, leading to a soaring crime rate in stolen ATI cards. Satoshi would instantly be the richest man that ever lived. It's a good thing Bitcoins are divisible to 8 decimal places

How are you guys getting 1.25v? I use AMD GPU Clock Tool to adjust core/memory speeds and while there's a drop-down box to adjust voltage, it doesn't seem to work and my voltage gets auto-adjusted to 1.088v. I've been running stable @ 1020MHz @ 410-412 MH/s for 3 days now without a problem, so should I even be worried about voltage at this point?

Yah I seem to get really lucky with hardware usually - my 5830 clocks to 1040MHz and cranks out 330 MH/s stably 24/7. Though on the other side of the coin, I have a 5870 that has problems with anything over 990MHz. Oh well, you can't win em all

Well that's a fair point. But as I said it's all a very complex mishmash. It is much more difficult for difficulty to decrease than increase. Once you have invested into bitcoin you are invested. If you are making $5 that's still $5 you are making. And the fact is that mining is still ridiculously profitable. Even after all the difficulty increases I see about 1000 USD profit per month off 5GHash in possibly the most electrically expensive area in the country. If I weren't electrically limited I'd be boosting the difficulty up myself. There's simply no reason to see difficulty drop right now. In fact if it weren't for the volatility of bitcoin scaring investors from plopping money into it, and the zero-sum aspect I think you'd see difficulty increasing far faster than it is now even without a price increase, at the current price.
But that still relies on price being the primary motivator, with awareness a subfactor. Difficulty remained relatively constant for the first year and a half or so because both awareness was low, and price was nonexistant. People added value to the coin without exchanges though, there was a thriving "over the counter" trade system created, and this combined with more awareness of the coin caused more people to get on board, raising difficulty.
Aside from the small (now minority) group of enthusiasts who mine bitcoin because they believe in it becoming an eminent player in the world currency, most people playing with mining and trading bitcoin are profit seekers, speculators, and other opportunists, who follow price. And most of the new players who become aware of bitcoin choose to join because of the pricing/profitability.
Basically you will never disentangle price and awareness, but short of a change in human nature as you put it, you will not see awareness be the primary factor in bitcoin mining being taken up. And that's why satoshi constructed it that way in my opinion. To take advantage of human nature.
All my opinion of course. Oh wrd. I hope you're right. If so, we can look forward to the possibility of a couple rounds of difficulty reduction, following the big drop from 30+ down to 11'ish we saw recently. At the very least, we can get some more mileage out of our current HW setups.

I just bought a used 5850 yesterday morning and I'm not sure what revision it is, but I'll check when I get home. I can clock it to about 1030 @ 1.088v. Anything beyond that though, and it becomes unstable. AMD GPU Clock Tool won't let me volt it beyond 1.088v. I've had it running at 1020 for the last 24hrs or so without any problems and it's hitting around 412 MH/s. The power connectors are at the very end of the card (short edge).
