Yes, it is Possible for you to install Mac OS X 10.6. Well known as Snow leopard on a PC.  It is not as easy as 1,2,3. There are several steps that 
have to be taken under consideration in order for it work; and not in all cases will work properly. It is best or recommended to do it with Intel
Processors- Apple “Steve Jobs” has made it hard enough already to make all components to be compatible only with this type of processors
even with motherboards, Since Mac OS X uses a different infrastructural or system instead of BIOS. It is also possible to do it with AMD
processor, personally haven’t done it myself but you are more than welcome to try.
I’m not saying is not impossible but it is best recommended on Intel processors. As far video cards… Well personally- please do your research. 
There are several Video cards that are compatible.In my case, I have a Nvidia GeForce GTX 550 ti, in which is only compatible with
Lion OS 10.7. I will explain in details. Also follow the links for more information on links, articles and even video tutorials.

I have a Nvidia Geforce GTX 550 ti - Unfortunately is not fully compatible with Snow leopard. I have tried numerous times to get this done, 

I even tried to install 10.6 Server. I do get decent quality picture but…. That’s not the point. At-least on my side it has not been possible for the

OS  to recognized my Video card. Please do your research before purchasing you Video Card. Please follow the link below, it is constantly

updating and adding new supported video cards to the forum. Please click on the link and see comments from previous users.

At this point the GTX 550 ti- is only compatible with Lion- Getting the retail OS is kinda hard since they only want you to upgrade right from the 

iTunes store.
