Wow, just wow.
OP buys mining rig and hasn't even researched or understood the concept of difficulty levels before hand.

Fucking golf clap good sir.

This is what I did when I bought another 2 GPUs (5850s) to my PC (only had a 6850 be4), but I don't regret it, mining is still profitable with 0.9 Ghash/s.

I am considering a new motherboard purchase in order to add more cards to the system. I see various specs that say PCI-E X-16 slots and X-8.

I am not sure what the X-?? means or if it affects mining.

Any suggestions or clarifications?

Any recommendations on motherboard specs to look for?

X is a prefix for *
the number behind that specifies the amount of lanes that are connected to the PCI Express bus.
x16 is usually used for graphics, as they need most of the bandwidth.
x1 x4 and x8 are usually used for generic devices.

I perfectly understand the concept of difficulty it is just that I don't speak english very well so you don't understand me ^^

I know that difficulty goes up of the power of the network goes up but I want to know the relation between them

for exemple :
power of the network = A
Difficulty = B

A * X = B

I want to know X

(I am sure that the calcul is more complex)

See this link https://en.bitcoin.it/wiki/Difficulty it explains everything I think you need.

ok, but can we know the next difficulty if we know the total GH/s of the network?

http://bitcoinwatch.com/ Under Blocks you will see difficulty and next difficulty.

ok,

But how does the difficult grow up?
Is there a mathematical relation to know it?

The system is designed to maintain a certain rate on finding blocks.
This is 6~7 blocks an hour. 1 each 10 minutes.

If this rate highers cause people buy mining gear and start mining then the difficulty will be higher next difficulty reset (happens each 2 weeks).
If people stop mining and the network capacity goes down then the difficulty goes down so it will maintain the build in rate of finding blocks.

The only question is when it goes down... nobody knows.

I have a dedicated Linux miner with 2x Sapphire HD5850 Xtreme and they clock to 980 MHz and 1020 MHz respectively (so far I'm only 16 hours into the test but it looks promising). This is without flashing the BIOS or mucking around with voltages (stock voltage is 1.0875V) or touching Windows or DOS. This nets me 826 MH/s so I'm sure you can get a little more than 300 MH/s each out of these cards. Don't be confused by the many threads concerning the reference 5850's, these cards are far superior when it comes to mining.

Be warned that there are some problems with the fans on these particular cards so it would be wise not to push them to 100% for too long but at stock voltage you should be fine at 70% or so.

Let me know if you'd like some details.

Oh, and you can overvolt your cards on Linux without flashing card BIOSes or using Windows/DOS.

ok,

but I think that invest in BTC is like invest in stock (bourse in french like NYSE... don"t know how to say) we invest money that "we don"t need"
I do this for the beaty of the thing and obviously earn money if it is possible.

But how does the difficult grow up?

you all make me scared, why people are mining if the will not be profitable?

People already has the hardware payed or almost payed. If you check since the last two difficulties increases, the hashing power of the network has grown less. It means people is not investing much in mining hardware. Its less attractive to mine right now. If the price exchange of bitcoin goes up you will be profitable. If it does not, hope that difficulty stays low...

And if the price of bitcoins goes up, you would have done a lot better just buying bitcoins and holding them than investing in mining equipment.

Dont get scared. Im just pointing to you the facts so you know what is in front of you. Nobody knows what will happen in the future, anything could happen. Im just pointing you the posibilities.

TY Clipse, but I don"t know what "RBE bios mod @ 960/180" mean (I am french) can you explain it?

With the next difficulty I will earn $144 per month and I will make benefit until a 3 500 000 difficulty

This difficulty rise will be only around 10% increase. The two previous ones were both over 50% increase. If the price of bitcoins does not go up, you wont recover your investment probably.

First of all, those cards can do 390 with no voltmod simply run them with RBE bios mod @ 960/180 , if you have voltage control those cards will do >400mhash/s ~420mhash/s is a good estimate if you tweak down the voltage properly and keep it cooled decently(air will do, if enough fans to blow cool air)

I hope for you next difficulty increases will not tear your dreams appart.
Next one is in about 220 blocks from now and is gonna lift the difficulty up with 13.4%
Good luck.
