Choosing PCI cards for mediator.

[Gulliver]

I would use both a radeon 9200 (256MB) and a voodoo 3 3000 as graphics cards. This is why:
-Radeon 9200 is also use compatible with AmigaOS4, MorphOS, AROS. You never know...
-The Ati Radeon Pro 9200 is a 128bit device while al other Radeons, including 9250 series are 64bit
-With a Radeon, you can use most of the 256 MB as Fastmem, lets say you use 250MB!!!
-The Radeon can coexist with the voodoo
-The voodoo 3 3000 offers warp3d drivers, and a mature driver, and the fastest voodoo performance. Other voodoo´s, like voodoo 5 5000 are not fully taken advantage and will eat a lot of PSU power

If you want an ethernet card, use a RTL8139, which is a 100/1000 card that you may find very cheap, like 5 USD.

Well, then according to your previous statements, then the voodoo 3 3000 is the graphics card for you.

About ethernet cards: as you have guessed the bottleneck is allways the Amiga, so basicly you wont get any big enough difference, so if you already have a supported ethernet, use that one.
