What do you mean by high speed? If you mean GigE then I'd move to a
fiber card with a 64bit bus. We use the Syskonnect SK-9843 here and its
really top notch. I don't know much about copper GigE cards as we just
don't use them here.
If you mean 100bT then the Intel Pro cards are good. We use them a lot
