New GTX 650 ti Boost

Got one of these today Gigabyte GTX 650 ti Boost. Set Graphics Enabler to No, downloaded latest NVidia driver, added to Boot.plist changed system definition to IMac 13,1 then rebooted and all is well.

Hope this helps someone

Edit: Had an issue where with this card it took a solid 2 minutes for the computer to post. Ended up being a UEFI issue but Gigabyte had a bios update post 3/13 fixed it.

Hi,

I have a 650Ti Boost, too and when i plug it in my computer won't boot at all. It took yours two minutes to boot? Maybe i should try that.
I am using a 500w corsair bronze psu, are you having more power?
what was the issue with your uefi? I have a gigabyte ga-b75m-d3p with bios/uefi f4. Do you think i need to flash my bios to f6?
thank you in advance for your help.


Edit: flashed my bios to f6, installed the nvidia drivers, put in nvda_drv=1 and still nothing happens. No usb keyboard working on bios boot screen and no boot into chimera or mountain lion
