You may want to think twice about getting the AV8 3rd eye. There are bugs that need to be sorted out, like not telling an accurate temperature (mine used to say 12*C - until bios flash) but now I can't overclock with the pci lock on.
I have heard the the msi neo2 platinum is a excellent motherboard if you have to hgave agp, but otherwise, DFI lanparty is the best motherboard out (only pci express graphics cards at the moment though.)
The amd 64 3000 is a excellent cpu, I have one, and I am very pleased with it.
