9600GT not working with Mountain Lion

Hey guys!

Need some help in installing the 9600GT in mountain lion 10.8.

My system:

Intel i5 3470
Gigabyte Z77-DS3H
G.Skill Ripjaws 2x8Gb DDR3 1600Mhz
SSD OCZ Vertex 3 Max IOPS 120Gb

Everything is working right with the HD 2500 64MB Shared...what can i do to install the 9600GT

It's a Colorful Geforce 9600GT 512MB (worked out of the box in LION) that i would like to use instead of the HD2500 but when i plugged it in just shows a black screen during boot

Any ideas???

Thanks in advance

Its not something you install, its something that your hardware cpu has. Unfortunately your cpu only has hd2500 not hd4000

Thanks dude, didn't knew that 3470 had the HD2500

Then the problem now is how to get the 9600GT to work...any ideias about it?

Thanks again
