Actually, I disagree... not everyone directly compares the cost of buying something to the cost of power. That power comes from somewhere, in my case, from coal power plants...
In addition, I'd like to upgrade my son's computer, he has a Dell with a limited power supply. I could of course upgrade that, but if the card needs less power, I can put it in without a bunch of modification.
The other benefit is the mid tower case that Dell provides doesn't have a ton of airflow, a cooler running card needs less airflow and thus less of a case to put it in.
It also reduces the AC bill, which in Texas, adds up after awhile.
For gaming, three displays is the sweet spot, but nVidia's surround isn't up to the level of Eyefinity yet. I tried it with a pair of 780 TI cards and it just isn't as good as Eyefinity.
The connectors aren't the issue, the power output of the power supply and electric bill are.
The 770 needed a stronger power supply than the 970 does. You can get away with perhaps 50-100 fewer watts in you PS and it saves money over time in your power bill.
Why add more? To sell more stuff on iTunes, that's why.
We have a pair of 16GB iPads. They are chock full and have been for awhile.
Some apps are approaching 2GB each now (Real Racing and Infinity Toy Box are two examples).
We could fill 64GB without any trouble. It would be nice to be able to download more than two movies for offline use as well.
If it were priced reasonable, I'd be happy to pay a bit more for storage. But when a 256GB SSD is approaching $100, it is insulting to charge $100 for 48GB of storage. Double that when you consider the SSD has no other income stream (iTunes) and has to come with a controller and processor. The iPad/iPhone already has those, so the jump from 16GB to 128GB would cost Apple perhaps $20.
Even selling that for $100 is nuts, but fair enough.
Yes, but it consumes less power than the 770 it replaces.
Also, it only barely needs the second connection, that is likely there for margin and overclocks, it could probably run just fine at stock clocks with a single PCI-E cable.
What is nice to see is that these cards are slightly faster than the generation they replace, while using less power.
The power use of video cards has been creeping up in recent years, going up to the point where a pair of PCI-E power cables was required for one card.
Nice to see a fast card that can be put into a modest system, the 970 is 20% slower than the 980, while costing 40% less money and using only 165w of power
That is low enough that it should work with most cheaper rebuilt systems from the likes of Dell/HP/Acer etc.
Here you're naively presuming AES 256 is substantially more secure than AES 128. I suggest you google what Schneier has to say about it.
No, what I said is that AES-256 can't be brute force broken by trying all possible keys.
There are too many of them.
There could be other ways to break them. The easy example is to find the person who knows the key and make them tell you.
Other examples are in a flawed implantation or sloppy programming of some sort, or some other trick to find out the key.
But you can't brute force break it. The key space is too large. You could take all the computers in the world and give them a billion years to work on it and they wouldn't make a dent.
:) I used to be a computer hoarder... I actually still own an Apple IIgs and even an ImageWriter II color 24-pin dot matrix printer.
Why? Well, the computer makes sense, I want to show my kids what computers were like when Daddy was growing up, the printer? Meh, a huge paperweight I guess, but you can still buy ribbons for it.
I used to have a 386DX-25 setup, a 486-DX/2-66, and a Pentium 166 MMX, just "in case" I wanted to play around with older stuff.
I have since thrown those away, I turned them on about once every other year, for about 2 hours.:)
I do still have a Pentium 4 under my desk with Windows 98 on it. It works, the RAM and hard drives have been upgraded in it, but really, what am I keeping that for?
Under another desk I have a Core 2 Quad Q6600 machine with Windows XP on it, but frankly, it hasn't been turned on in 3 or 4 months. I have it "just in case" I want to run something on XP.
You have no idea how hard it was to throw out the three older PCs, but you know what? I don't miss them. You can't keep everything (or you shouldn't) and they really weren't being used.

Speaking of digital data, this summer I discovered Amazon Prime Music, a recently added feature. I have a ton of ripped music on my computer and copied to my phone and iPad... you know what I've discovered? Almost everything I listen to is now free on Amazon.
Between purchased shows and movies and all the Prime Videos, I have more entertainment than I can really ever consume.:)
I'll have a desktop for a long time, if only because I need a full size keyboard, mouse, and large monitors (I do software development so I have three 30" monitors at my desk, I can't do this from a laptop).

The funny thing is all the RIAA/MPAA lawsuits did nothing to get me to stop using Torrents (which I used to do 24/7).
You know what did? Reasonable cost options and ease of use streaming. Giving me legal options killed the illegal options cold. It took them long enough...
About 2 years ago when I put the Roku boxes in place, I deleted over 40TB of movies, most of which had never been watched. Crazy waste of time and money, oh well...:)
The freaky part? My electric bill went down about $50 a month once I got rid of the server and DVD/BR ripping computers which ran 24/7. I put a kill-a-watt device on them and found they used about that much power each month, for 6 years...
Frankly, I setup my home 8 years ago (when I bought it) with a server room in one of the upstairs closets, had the whole house wired with Cat 6, got a 24 port hub, setup a server in a very large case with 24 1TB hard drives (those were expensive back then), and went to town.
Over the next few years, those drives were replaced with 1.5TB, then 2TB, then finally 3TB drives...
I had a second machine in place when the Core i7 920 came out and used that to rip DVD and Blu-Ray discs using AnyDVD to crack them so they could be served.
I had a computer on every TV in the house (all 4 of them) and was going to town...
Until one day, I discovered I was spending more money and time than just BUYING THE MOVIES WOULD COST.
Yea, nuts...
So I ditched all that, deleted a LOT of hard work over the years, and now buy all my movies via Amazon Instant Video.
Why? Because the quality is nice, the convince is easy, and I now have more time to play with the family.
Of course, 8 years ago, the streaming video options were not as good as they are today, which is why I set it up in the first place.
But frankly, it was a huge waste of time and money.
Today I have nothing in the server closet, other than the 24 port hub, my main desktop downstairs now has four 4TB drives that store eveything I care about and 2 external 3TB drives backup the critical stuff.
Two different online services (Crashplan and Backblaze) back everything in the house up offsite), and I also keep a copy of the most critical stuff (family documents, pictures, and videos), on OneDrive.
My wife's computer in her office has a copy of all that as well, and her documents, and of course they are all networked.
The computers at every TV? Gone... replaced first with Roku devices, now replaced with Amazon Fire TV devices.
Life has become much simpler, I have more free time, my electric bill is much lower, and frankly, I spend less money buying movies than I ever saved "ripping them".
The question then becomes... does technology help or hurt the cause?
Throughout human history, it has always been possible to move to someplace new, to travel to the new world, so to speak.
That is quickly not becoming possible. To some extent it isn't possible now, but it can be depending on how far off the grid you care to live. But that time is ending.
But it does not have to be that way. Your phone does not need to indiscriminately produce a "data exhaust." It was just designed that way by people who want to capture as much of your data as possible.
Don't let your apathy and ignorance get in the way of the people working to make things better. One day you might decide that there work was actually useful to you after all.
While that sounds great, it also sounds a lot like swimming upstream, pissing in the wind, etc...
Frankly, while I applaud your efforts, I think that you may not be accomplishing much.
I've read up a lot on AES-128 and AES-256, I was not aware of the difference with RSA...
What I do know is that as far as I can tell, there does exist encryption that is strong enough that no one can crack it. If someone can, they are being REALLY quiet about it.:)

Since you can sell (or otherwise use) the 770, if you pay a premium rate for power, the savings over 2 years may well pay for the upgrade. :)
He isn't asking to watch movies, and it does t sound like games either, if he is willing to consider 30hz.
For desktop environments, more resolution is usually better.
Yes, we will start to see more of this as the process technology leaps slow down.
They will have to find improvements in the design of the chips, vs, for years just depending on making them smaller.
Even if no new process technology came out for five years, I suspect they could keep making theses better and better
For professional use, yea, that does suck...

Then you run into time and storage constraints.
You could have a trillion supercomputers running at a trillion keys per second, and you'd need trillions of times longer than the age of the universe.
How would you measure progress and store it?
The size of the numbers is larger than many people suspect, it is more an academic question than a practical one.
That is a fair point.
I will say, that has to change for the online streaming business to work.

There is this thing called Netflix and Amazon Video. :)

All true...
The question then becomes... does technology help or hurt the cause?

That is quickly not becoming possible. To some extent it isn't possible now, but it can be depending on how far off the grid you care to live. But that time is ending.
Yea, I get it, the world has changed...
Of course, there are many rebels fighting in the world today who are massively outgunned...
Northern Ireland, Gaza, Syria, etc...
A few people protesting, such as OWS, aren't going to change anything, but revolutions have started from less.
Should the American Rebels, completely outgunned by the British, have won?
Are M-16s useful against tanks? No, not really. But they are a start and you can't have tanks everywhere.
You make jokes, you laugh, but if you studied your history you'd see David wins agains Goliath more often than you might imagine.
Disarming the people is one way Goliath tries to maintain control, and in the name of "safety" you go along with it.
AES-256 will never be able to be brute force broken.
Never.
And I don't use that word lightly.
The energy to check all the possible keys doesn't exist.
You would have to come up with a way to run the math using energy from outside our known universe.
http://www.reddit.com/r/theydi...
Well, at one key per second, it wouldn't ever find the answer, now would it? :)
What I said was, checking all the keys would require more energy than there is in the universe.
