If anyone's selling, I'm looking to buy 3x IDENTICAL (brand) ATI 7950 or 7970 cards. It'll probably happen sometime this week. I might grab them at a store (newegg or similar) or something, because I doubt someone has 3 identical ones, but you never know.

Also, if someone's selling a decent mobo/cpu/memory (or any of the above) combo, for reasonably cheap, let me know by posting here - preferably with price please. I know sixer had triple-channel DDR3 memory, but I'm not sure if I'll need triple channel at this point - maybe dual or quad, depending on mobo choice which I haven't finalized...

The mobo MUST be nonshit brand (Gigabyte, MSI, Asus preferred), and must have decently-spaced slots for the 3 cards - PCIe x8 or more, not x4.

Oh, also if someone has a PSU that's at least 850W, 80plus certified and nonshit brand, also not overly dusty or old, also post with price :-P .

That's about it.
 
Post model and speed (mhz and CAS). I'm assuming it's ddr3...
 
Le bump, still haven't bought all the shit; will probably make a final decision by Sunday... so if anyone is selling stuff, let me know :-P .
 
Holy shit lol, I'm actually looking for the cheapest-ass possible memory, so that's probably way too expensive. I'd feel bad putting it into use for what I'll be doing... which isn't games actually... but yeah, thanks.

bit coin mining?

I was thinking of getting 3 (9x7950's), but I'll start slowly and maybe get moar in a month or two.

I'll be running at home to start with, welcome high electricity bills, yay.

Whats a good resource on learning about litecoins?
 
I kind of read a lot about hashing in relation to password cracking, here: Why passwords have never been weaker and here: How I became a password cracker | Ars Technica

Incidentally, hashing is also very related to mining (in fact, that's what mining is - hashing with adjustments to "difficulty").

In short, bitcoin is based on some hashing algorithm which is easy to build ASICs and FPGAs for, so when they come out they make CPU/GPU mining obsolete.

Litecoin (and other cryptocurrencies - there's actually many, and people are thinking about releasing even moar - most of them are blatant copies ("forks") of bitcoin) is based on a different hashing algorithm which is supposedly much more difficult to build cost- and energy- effective ASICs and FPGAs for. Not impossible, just more difficult. The hashing algorithm for Litecoin is called "scrypt." It can also be used anywhere else where hashing is useful (file checksums, password hashing, etc.).

In any way, I don't see this being profitable in the long run, and I'll probably be selling everything I buy today in about 6 months, but I should be able to make profit. The whole thing is extremely risky, since nobody knows what will happen with these cryptocurrencies; maybe they are "the future" and maybe they'll collapse completely or become obsolete...

There is one good point for a major weakness in most cryptocurrencies that I read about on some forum post and that is that there's no inflation built in, so there is incentive to hold and never sell instead of to use and transact...

Anyway, there's no "centralized resource" to learn all the shit from, you just have to pick it up in bits and pieces from forum posts mostly... and I don't have a full picture yet, but I understand the basics of what's going on.

I'd start by reading about overviews of hashing algorithms, like scrypt and the one bitcoin is based on (I believe that one is SHA-256) and the 2 password articles :-P ... Pretty interesting reads.

In other news, Google engineers are looking to replace passwords with something else - due to their increasing weakness. www.wired.com/wiredenterprise/2013/01/google-password/

I've started using Keepass myself, and generating 64-char passwords with high entropy whenever possible. I use two-factor authentication with a key file that is actually available on the internet, a 26-char password with a decently high entropy, and 3,333,333 permutations - so good luck breaking through that with current hardware. If you want I can send you my password file so you can try :-P - just let me know. I was kinda tired of being p\/\/n3d by "password leaks" on linked in, EA, winamp forums, etc. etc., and I thought that instead of reusing the same password or variations of it, that I could do MUCH better than that - being a geek and all... :-D . So I did.
 
Thanks for the info! I've been meaning to do some more research, but I am just now getting caught up on all this bitcoin stuff.
Very interesting - and thats party because it IS so volatile.
