    I've had two GT120's in my 2009 MacPro/12Gig 4x450GB15K RAID for over 18 months with no KPs...but mostly running one display...a 27" iMac using the Apple proprietary cable...the miniDP version of this cable:

     

    http://store.apple.com/us/product/MD861ZM/A/apple-thunderbolt-cable-20-m?fnode=5 1

     

    Upgrading to the varios OSs along the way to 10.8.4. 

    No problems.  On for months at a time.

     

    Recently, I got an LG 27EA83-D that does 2560 x 1440 (same res as iMac) native running off the DVI of the GT120 as I deployed the iMac at my office and needed a panel for the MacPro.  No problems.

    Then I bought a second LG panel, discovered what many know here that you can't run 2560 x 1440 off the passive miniDB to DVI or HDMI...so I plugged it into the second GT120 DVI port.  Rigged it actually for four panels...Powerpoint is totally wierded out...doesn't paint or update correctly if the second display is running off a different board.  Hmmm...

     

    So I get a KP while I'm "doing nothing."  Hmmm...  Then another.  Then another.  Then another...

    I'm getting them consistently using Safari and LogMeIn.  Can almost set my watch.  Hmmmm...

     

    Anyways, I too ordered the 5770...hoping to drive four displays...two at 2560x1440 and two at 1080p.

    What else do I need?

     

    Thanks you for everyone who helped debug this.

    FYI:

    It seems that the 10.8.5 update and/or new NVIDIA driver have... drum roll ...fixed the KP problem with two GT120 graphics cards on a Mac Pro.  That has been the case with mine, at least.  Using Safari in two monitors with multiple tabs and lots of browsing has been entirely uneventful this past week.  I couldn't go a half-day without a KP before this with similar use.

    I updated 2 days ago to 10.8.5 on my Mac Pro 4,1 with dual gt 120s with latest nvidia drivers and haven't had a kernel panic since.  I was experiencing at least one KP a day.  Time will tell if it does it again and I will update this discussion if I get another but so far its looking much improved.

    Solid as a rock on 10.8.5.  No kernel panics in days running many applications.  System hasn't been powered down.  Does look like its fixed.
