Hi.
I have the same graphic card, but MSI model (GTX 650 1Gb).
VoodooHDA doesn't work with my motherboard, so I use a patched AppleHDA that works perfect.
My GTX 650 uses mini-HDMI port, but useless because didn't work (blank screen).
Both DVI ports works perfect @ 1080p, but not HDMI.
So, if I try audio, then need to re-patch the AppleHDA.kext to enable audio?
Thanks
Specs:
Mac OS X Lion 10.8.2
Intel DualCore E2200 2.2GHz @ 2.8GHz
Gigabyte GA-945GCM-S2L
Kingston 4Gb DDR2 600
MSI GeForce GTX 650 OC Edition 1Gb GDDR5
Corsair ForceSeries F115 SSD 115Gb SATA2
Seagate Barracuda HDD 500Gb SATA
Also say that I needed the modified official nvidia drivers to install it on 10.8.2 (probably SMbios problem),
after reboot it shows perfectly and OpenCL working (WoW works perfect). Also installed CUDA driver.
