Need help choosing a motherboard!!!!

[knoxville]

Hi guys,
I've decided I want to build a bitcoin mining rig, and I want to have 4 Radeon 5970's. Basically, I need some help figuring out what motherboard I should use.

To get the best mining rate, I want all 4 cards to run x16 speed, as opposed to, for example, 2 running at x16 and 1 at x8 and 1 at x4.
I'm kind of confused by it all to be honest. But apparently to get the best mining results, all the graphics cards should run at x16.

So do any of you know of any motherboards that could do this? And at the same time, will fit 4 Radeon 5970's?
Hope you guys understand what I'm getting at, and any help is appreciated!
Thanks

I tried to put it into the motherboard section, but there wasn't a subsection that was relevant, so I put it here. Not sure how to move it though.

there isn't much of a difference between 16 and 8x almost none.

Im staying away from bitcoin mining because in a few years when they realize people are generating random currency i believe they will start slamming people hard with counterfeit lawsuits. with that said having a motherboard that will do 4way crossfire, and unless your using a linux based rig that doesn't need crossfire bridges than you can only use 2 5970s, there dual gpu cards.

Hmmm maybe, but the price of 1BTC is $47 at the moment, and I think I might try and get a few at least. There's a lot of people predicting they'll be worth around $1000 in a few years time.

So I can only have 2 5970's at once?

If your using windows than yes only 2 5970s, and you would only need 2 16x slots.

Ok thanks!
But do you know of anyway to get all 4 of them to work? Sorry for all the questions haha I'm fairly new to all of this.

Im not sure if you can do a 4 way 5970 on linux or not but i have heard that with some programming you can use 4 video cards with no crossfire or sli cables on linux,maybe look into that.
