I have two pre-orders for the KnCMiner Jupiter 1-500.  Each of these units will provide a minimum of 350 GH/s!  At today's difficulty that would mean a profit of $51414.81 per month.  KnCMiner says that these units (the 1-500 batch) will be shipping in September.  The order numbers are 401 and 382.  I am willing to sell one or both of them if anyone is interested.  The reason that I'm willing to sell is because I would rather sell now for a quick buck and reinvest elsewhere, plus my gf and I are getting ready for a big move and it would be nice to have some more money for that.

According to this thread https://bitcointalk.org/index.php?topic=221312.msg2359904#msg2359904, the pre-order can be transferred through KnCMiner.  

Having not done this myself, I cannot speak from experience .  

I am located in the U.S. and can provide skype, and a phone number if you would like to discuss the deal.

Please PM me your offers and weather you want just one or both pre-orders.

I've been running two HD7970s for about two weeks and just ordered two HD5970s to add to the mix.  Today I tried installing the HD5970s and the screen kept going blank for a couple seconds then returning, so I thought there might be some driver conflicts.  To help diagnose, I unpluged the two HD7970s and ran the two HD5970s, but there was no video.  

Has anyone run this configuration before?

I did find a forum that claims the 10.5a display drivers work best for HD5970s.  Will these drivers work for the HD7970s also?

Any help is appreciated

System specs:

MB: Asus P6T Deluxe V2
Mem: 12g
CPU: i7
PSU: 1000 Watt 80+ Gold (will be running 2 x 1000 watt PSUs when I have all four cards installed)
Cooling: Big box fan and plastic storage crate

Curious if anyone has tried anything like this:

Looks like it would allow for using only one mb, processor, and set of dimms for a giant mining rig.

Any idea what the issues might be if you ran one of these with all x16 slots used by gpus?
