So this rig

• Windows 7, now running Ubunto 12.04
• Gigabyte AMD Radeon HD 7970 OC 3GB GDDR5 DVI-I/HDMI/2x Mini-Displayport PCI-E 3.0 Graphics Card GV-R797OC-3GD
• MSI V2 Socket AM3+/AMD 990FX/DDR3/CrossFireX and 3-way SLI/SATA3 and USB 3.0/A and GbE/ATX Motherboard 990FXA-GD80 V2
• AMD FX-8350 FX-Series Eight-Core
• Power supply TR2 RX 1200W
• Antec Kuhler H2O 620 Liquid CPU Cooler System

Is happy running 2 7970.  If I add a third, the fans on the third do not run.  Does not seem to matter if I

• use one or another of the slots
• use an extender, with or without powering the molex
• use a 100 ohm resister to fake out a display attached
• use a 2nd power supply for the 3rd test card

Basically the fans should be running after the POST startup, so I do not think it matters whether Windows or Linux at this point.

What to do?  How do I run four cards, or maybe it can't be done?

So I just now exited a screen on a demo software, was going to buy it for $25.  Because on that Purchase License screen ... I saw a whole page of entry blanks.  Maybe 18.  Probably a couple of emails after that.  Probably a new litany of spam.  

And I quit.  Don't need it that bad.  Don't want to waste the time.

Now if they'd just asked for their 0.2 BTC and one click....

You name it.

What will it be?

What is the bitcoin's relation to the plot?
