Dual GTX 650 and GTX 670 powering 5 monitors 10.8.3 Apple Drivers working OOB.

So, for a few years I have been running my system (see signature) with a Radeon 5770 since my 6970 refused to work. This allowed me to run 2 screens. Yesterday I picked up a new GTX 650 and GTX 670, installed in system.... gtx 670 in slot 1 powering (27" 2560X1440 DP) (23" 1080p DVI) (23" 1080p DVI) and the gtx 650 in slot 2 powering a third (23" 1080p DVI) (32" 1080p HDMI).

This is all running off stock apple drivers 10.8.3 with cuda installed. Nvidia drivers installed also but not active or required for above configuration.

I have not benchmarked the graphic cards yet but the opencl test galaxy app shows it maxed out with the 670. For this system, which is a bit older, I get a geekbench of around 12500 with the 32 bit test.


I did have some problems initially trying to boot with all 5 screen but a new version of Chimera (2.1) from and full redo of Multibeast did the trick. I also managed to fix the slow slow boot issue too but I dont know if that was from one of the power management kexts or what.

Either way, here are the pics.

Very cool! Are you able to do extended desktop with this and rotate any of the screens? Like make them portrait mode? Did you need to modify anything in DSDT? I'm looking to create a 4-monitor setup with 2x GTX 650s. All the same monitor but they'll be arranged side-by-side in portrait mode and need to be one big desktop.
