osx86 on my rig

Ok so I was just wondering if people could give me some input on how well osx86 will perform on my computer. Also which would be the best "distro" to install.

I have a

MSI P7N Diamond (780I)
Q6600
4gb of ddr2 1066
and an EVGA 8800 GTS

Any comments and suggestions are welcome.

I believe you have to MOD your BIOS, you can ask for yours here, or try DSDT Patcher with Chamaleon with DSDT Override, check this guide too
