Agreed.

heres one.

Oh definitely.  I'm not expecting any sort of return on investment from this coin, not for a while.  Volatility is part of the turf, especially with new coins, but I see it as a cryptocurrency breakthrough, which I hope moves other people who are considering unloading more cutandpaste coins to cease and desist.  Unless there's something new or unique about the coin, I'm not interested. But that's me.  I'm most intrigued by how crypto currencies in general will change the world. ( enter evil laughter here )

this. Is. AWESOME, just what I needed alongside my coffee.  XPM has my vote for long term, although I'm not personally in it for financial gain, but simply because they've done something to deserve it. the amount of power used in the United States to mine each day is upwards of 80k.  For useless work outside of getting coin. I'm prefer my power going to some other greater good besides finding block chains. t also makes me think we need to get on some wind power or solar power or something, cuz jeez that's a lot o money over a year in mostly wasted energy. (Unless you're heating your house with a rig )

good stuff! I have high hopes for primecoin, as its development, like people have already said, uses all that extra energy ( did you know mining in the u.s. costs us 80+k in electricity a DAY? That's only going to get higher) to work.  The most intriguing thing I found was concerning a computational program from Stanford to help find cures to some diseases.  The other half is to find longgggg prime numbers, which I guess is a big thing in the math world?? were talking world record, million digit long primes. I guess primecoin has already slashed a world record for long primes.   It beats me as child with the Guinness bookofworld records out, trying to stand on one foot to beat the record, which was days long.

But seriously, it's the first coin that isn't being mindless about all that expendable energy, and I for one applaud that.

So! My fiancé and I have decided to go with our first investment in building a pc mining rig.  We got two radeon hd 7970s coming our way.  He wants to expand the GPU to at some point take on 4. We realized the biostar motherboard we ordered online http://www.newegg.com/Product/Product.aspx?Item=N82E16813138372. Has:

Expansion Slots
PCI Express 2.0 x16
2(x16.x4)
PCI Express x1
2
PCI Slots
2

So, should we

A) get another mobi to take on that kind of expansion, if yes, which Moho do you recommend? We don't want to spend too much on it.  or

B) is there another way to expand the gpus like with risers? I haven't built a computer for a decade, so im kinda behind on what's what in today's tech world.
