You want more than a 650 psu for 2x7950.

you can run 3 on a 750 so 650 will be fine for 2 cards

   cost
i would say look on ebay find a cheap motherboard with 2 pcie slots am2 50
get 2 7950 vaporx oc edition ( dual bios ) i know there more mony but thay are beter cards 490
cheap am2 cpu 20
4gb ram 20
psu hx 750 used 70
cheap hdd 10
   total 660

You can't run 3 safely OR efficiently on a 750W, please learn what you are talking about before speaking.

You can try 3 x ATI 7850, they cost less and spent less power...

MB GB H61M-DS2V - 51$
CPU Intel G1610 - 45$
HDD no matter - 55$
RAM 2GB DDR3 - 18$
PSU SS 620W bronze - 85$
3x ATI 7850 1GB DDR5 - 3x175$

If power is not a concern 5850's can be bught for $125 us and get 400khash overclocked

Find a cheap open box am3 or am3+ motherboard at your local store.

single core amd sempron

cheap ram and a good power supply

with 3 5850's 1.2mh and all together can be had for 575 us dollars
$50 motheboard
$30 cpu
$20 ram
$100 power supply
3x 5850 at $125 =375
Total = 575 say 600 for shipping ect.

EDIT: actually they consume 175watts each so not bad on power either

aren't 2x7950 better?
they run at 600 each and wattage is 200-225 max

Yes they are better but can you get 2 x 7950's for $375?

Your basically looking at $100 vs 100watts

100 watts = 40 cents a day .40 x30 = $12 a month so about 9 months until the 7950 pays for the extra $100 price

The 5000 series are strange cards. My 6850 maxes at 275kh it doesnt care wether the memory clock is 700mhz or 1200 mhz still 275kh. My 5850's run at 400khash at 975 core and 1175 memory. If I change one up or down without the other i actually loose hashrate. My 5850's blow the 6850 out of the water. I know the numbering system was differant back then. I think a 5850 is comparable to a 7950

Look at the am3/am3+ motherboards here. search for one with the features you want => search ebay etc for used ones

400+90+60(mob+cpu+ram) even used mob, cpu and ram are ok, i don't need them new

if it is still impossible, than 600 at max should be enough

nah, i can find them used at 200 each

There's still no chance of it being 550 EUR, decent PSU is probably 90 EUR (which you NEED).

i need advice, on a cheapest mining rig with just 2 vga, with no case

MOB: cheapest one, there is anything around 50 euro?
CPU: adm or intel?
RAM: 4 gb
VGA: 2x 7950, gigabyte maybe? or vapor-x?
PSU: a 650w would be enough, tell me the best
HDD: no issue, i have already one

it's possible to stay on 550 euro at max, $750usd

2 x 7950 already cost more then 500 euro...
And go for AMD: cheap mobo cheap cpu, good enough performance

my electricity is $0.17, i think i'm in profit, mining the most profitable alt-coin like dgc, wdc, ecc...
i can make 100 euro at months, so roi 6 months or less

Have you calculate, is the worth of electricity etc worth the cost of mining?
