HELP ME- minin rig hardware

[avialias]

Hi...

Please help me choose hardware for multi GPU  mining rig.
Rig will be used only for mining, not for other stuff. I have another PC for that.

So, I got 4 HD5870s, but I need other hardware , MBOs , CPUs , DDRs, POWER Supply

What do you recomend???

For
CPUs : AMD athlon II x2 250      yes, no
MBOs: need something with 2 x PCIe x16   yes,no
Do,the MBO, have to have onboard GPU, or not??? Where do you connect monitor if you dont have on board GPU?
POWER: how big do I have to have? more than 800W or more than 1000W

What do you use?
DO I have to worry about current that goes through a MBO to 2x GPUs?


What mining software to use on multi GPU rig?
Is it better to be in mining pool or to mine by me self...

PLEASE HELP fast...

I saw https://en.bitcoin.it/wiki/Mining_rig, but I cant buy that stuff at my country...

CPUs: AMD Sempron 140 (probably the cheapest available CPU) will do fine
MBO: no PCIe x16 needed for mining, x8 works too. OnBoard GPU is useless, connect monitor to one of your 5870s
PSU: for dual-5870 650W will be more than enough, 12V-rail has to handle enough load though (calculate ~200W per GPU and you're good).

What about that 12V rails???

are rail on power supply or on MBOs?  sorry i dont understand..please explain...

PSU of course, check its specs to see how much power can be drawn on its 12V rail(s).

as mentioned, for a 2x5870 (<400W) rig a 650W PSU should do fine,
i'm running 1x5850 (~150W) + 1x5970 (~300W) on 650W 24/7 for a few months now without any problems.

How much Mh/s do you get???

And how to setup minier and which miner software to use???

Are you mining in pool or alone???

some (that 5850+5970 setup just one of my rigs, i got a few more),
you can expect 350++Mhash/s on each of your 5870s, so it's 1.4++Ghash/s on 4 of them

And how to setup minier and which miner software to use???

depends on OS, driver/SDK version, and not at least you preferences

Are you mining in pool or alone???

both 
actually on my own pool, but i'm the only one using it so far.

12V rail at 20A = max 240W
V*A=W
