help building a gpu mining rig

[shilex]

hey guys;

can some one help me selecting witch rig to build
i am plaing on building a 7970 x 3 rig but cant find a good motherboard for cheap?

anyone got this setup up and running?

Check on craigslist in your area for old motherboards that have 3 pcie slots.  I don't think you should get 3 7970's though unless you have a killer deal on them.  You could by 3 7950's and with the money you save you could buy another one.  Same cost and 2200mhs>1800mhs

[shilex]

yes but witch mother board has 4 x pcie 16?

in belgium (where i am from )

Sapphire Radeon HD 7950 3GB GDDR5 With Boost / 250
and a 
VTX3D HD7970 3GB GDDR5 X-Edition 330
 

what kinda motherboard would you advise?

[notaek]

What processor are you going to use?  I just need to know what socket the motherboard needs to have.

[shilex]

i dont care if it is intel or amd you are free to give your opinion mate

Yeah that looks really good.  You could even get 5 gpu's on there if you wanted.

can i put a gfx in a pcie xa port?

[d-unknown]

any z77 motherboard with 3 slot pcie  will do the job, you can use it with a cheap g620 pentium dual core

[shilex]

on the board i said i can run up to 5 cards?

[shilex]

what kinda psu would i need is 1250 ok?
does anybody knows the performance/hash difference between x1 and x16 pcie?

For bitcoin?

Step 1: Don't.

Step 2: Mine Litecoin and invest in an ASIC bitcoin mining device. \

Step 3: Watch your Litecoin mining for 2-4 months while you wait for ASIC delivery.

Step 4: Get drunk.

How about this board?

You get 1 x PCI Express x16 slot, running at x16 (PCIEX16); 1 x PCI Express x16 slot, running at x8 (PCIEX8); 1 x PCI Express x16 slot, running at x4 (PCIEX4); 3 x PCI Express x1 slots;

Amazon.com seems to have it in stock, but newegg.com says it's discontinued.

I hope it's good, because I have one on order...

 why litecoin?
if i got it tight the motherboard supports up to 6 gfx's?

It can support up to 6 gfx's but only with PCI Express risers.

if i got your link right the best way to go is terracoin?

witch one would you advice jack?

BTC GPU mining is literally NOT profitable unless you happen to already have the entire setup, and don't pay a penny for your electricity.

ASICS for BTC or go Litecoin. Although, the difficulty increased a few hours ago from 150ish to 200ish.
