Would Mac OS X 10.5.4 run on a q6600?

My computer's processor is a quadcore, and I was thinking of installing Leopard into it, however before doing so, I was wanting to make sure that my processor would be supported. I know that Mac can run off an intel dual core, but I'm not to sure about a quadcore though. Yes, I am aware that all a quadcore is is two dual cores stuck together in the same CPU housing, but even so I decided it's better to play it safe than sorry. I mean...why spend $100 on something you can't use?

Also, for those who care, I use Vista (and XP), and with that said, it's not hard to figure out why I'm thinking a Mac may be the way to go. Personally I'd run Linux, but my computer seems to refuse to run even a Live CD version of it. @_@

Doesn't Apple prohibit installing their OS on non-apple hardware?
