Penryn E8500 seems to be promising ... 3,16 @ 4,7Ghz in air cooling ... And it will not be too expensive.
I know that for Intel users who already own a C2D it's not a real evolution but when you change from Athlon X2 to this C2D its another story.

And I will be able to get Leopard running with stock kernel and stock kexts on my PC ... That's really cool.
BTW: I'm working on a way to make Apple updates more easy for AMD.

About the upload of Rev.2 :

I've removed all rar from ftp as it wasn't the right ISO.
I will upload the new image this night and it should be finished tomorrow morning.
