Upgrading Mac Pro video card

I upgraded the Mac Pro’s stock video card to a Gigabyte nVidia GeForce GTX 600 with 2 GB of video ram. The card requires a special power cable: PCIe Power Cable for Mac. No local stores had this part in stock, so I ordered it from Amazon. It finally arrived so the card was installed last night.

I followed the video instructions below and had the card installed in a few minutes. It was a little disconcerting because when the system booted the screen remained black until the login screen appeared.

I’ve been running a few days with the card installed. The only problem I’ve had is that the system doesn’t always seem to come back from sleep. When that happens, I end up having to reboot the machine. Not crazy about this but I’m not sure what’s causing the problem.

More investigation, which means another post!
