Mac pro 3.1 eight core xeon processors with mavericks 10.9.2
120gb ssd in slot 1
The solo x1 has been shelved for time being
GTX 680 installed cuda drivers installed but not latest graphics drivers.
Windows 7 on bootcamp partition
Yep I have installed the GTX 680 but not the drivers yet (except for cuda).
I have kept the SSD in the hdd sata slot 1 as the keyboard drivers are not set up yet.
I have installed windows 7 on a seperate partition and able to boot between both without issue.
Am aprehensive to put ssd in pcie slot until all is well first.
Congrats so far!!! Make sure to make a CCC clone of your OS X and perhaps you could look into Winclone 4 to clone your Windows 7 partition. After your back-up routine you can try to get the SSD working on the Solo X1 in PCIe slot #2. Keep up the good works!
Cheers
