Build recommendation ~2.500€

[praktikant]

Hello guys,

I'm looking for a password-cracking build for about 2500€.
The machine should act as a Cracklord-resource (if you don't know what cracklord is: http://jmmcatee.github.io/cracklord/)... so it has to run Linux (I will probably Debian/Ubuntu)


Since I was looking for some nice builds, there came up some questions:
What are the best cards for this build? (e.g. 2x 980 ti || 1x titan x)
Is much RAM and a strong CPU important?


Thank you

Note that cracklord supports only a small subset of the advanced attack-modes from oclHashcat while it's those advanced attack-modes that a good cracker is looking for. Hashtopus and Hashstack (commercial) do have a much better control over them. I admit the cracklords webpage is good looking and it seems that they have a good marketing.

Thank you atom I didn't think about that.

/ But now back to my question, does someone have any recommendations? Either Cracklords hashcat plugin is going to be improved or I'm gonna code an enhanced version by myself.

// Just compared the benchs of GTX980 and GTX980Ti.. The price difference is like 15% the ntlm cracking speed 3% so i should prefer a GTX980 right? Or is there a catch?

At the 2,500 euro price point, you're still going to have the footprint of just 1 server/desktop so you may not need to worry about the CrackLord GUI yet until you start networking your other builds into it.

If you can get 980's for 15% less than 980Ti's, then you should do it.  Reason being: overclocking!

A very conservative overclock can EASILY yield you a 10% increase in performance on a 980. So what you will then realize is actually 7% performance over a 980Ti (10% - 3% = 7%)

You could also save $$ by buying cheaper brand ram, omitting the ATX case, buying the GPUs on Ebay, etc.

If you do go the saving extra $$ route, you could then buy 980Ti's instead and overclock those.

CPU should be an Intel i7 and go with 32 gb ram if you can, but 16 will be ok.

Thank you logistix111.

While I was searching for components i noticed that the new Skylake is supporting DDR4. Is this important for password cracking? (almost twice as fast) Or should i pick a Haswell CPU?
Should I pick a 4-way SLI Mainboard for expandability?
