As for me there is no best, or perfect Leo install either for Intel or AMD. Try install Zephyroth 10.5.2 Rev2 or LawlessPPC Phenom&AMD 10.5.4 relase. They both work on Athlon 64X2 CPUs. You shouldn`t have any problems with GFX Card - I have ATI and i`m not really in topic but i guess there`s a lot of kexts and installrs for GF6XXX Cards around. I`m not sure about nForce5 chipset - saw ppl reporting it as "no working" but im not sure.

So, what i`m trying to tell - you won`t find a relase which is perfectly matched with your hardware. You have to look for kexts, and solutions either way. So my vote - Zephy 10.5.2 Rev2 or LawlesPPC 10.5.4 - they install nice, without much problems, and they have kext folder on DVD image so you can put there all kexts you need to run installer properly - than You can solve hardware and booting problems ( with Vista the installer of DualBoot works without any problems - about XP there`s solution on this forum or insanelymac forum )
