Non technical answer:
I am looking for info on compatability of using Eyefinity and Lucidlogic Virtu. But I do have VIRTUE running on an i5 sandybridge z68 MOB.
I haven't hooked uo my 3 monitors yet. I'm waiting on a cable to be delivered.
But in case you don't know, if you use the discreet PCi-e GPU to attach a monitor,or monitors, you can, through the hidden taskbar menu, enable or disable the LucidVirtue software. When the Virtu window appears, there is a big button to do this, with immmediate implementation.
So you can in seconds, by-pass the Virtu software and have your 100% pure GPU's power. If you hook up the monitor to the Sandy Bridge CPU's onboard HDMI, this doesn't work of course, because if you bypass the Virtu software, you are not hooked to your 3rd party GPU.
