Dual processor advice

Hi;

I am building / upgrading a 2-proc. box, and I need some advice. I like the
asus line, and want to use it, but am not clear on which mobo I would be
best off with. I need two processors, and it should be reasonably fast, but
that's the only major criteria. I will use a seperate scsi card, so don't
want the onboard scsi (or onboard anything extra, really). The system will
be used for 3D animation and graphics dev.

There seem to beseveral choices: (PCH-DL, PCH-DLW, PU-DL, maybe others?)

I am wading through the specs, but if anyone has advice or suggestions, they
would be welcome.

Thx!
