Is there an appreciable speed advantage to using the raid technology and 2 drives?(stripping?)

I currently run a Abit KT7A-Raid with 1200 mhz in Raid-0 configuration.
Raid-0 provides a significant disk speed increase.

What video card should I get?

A Geoforce 2 MX card would give you a good price/performance
ratio. Geoforce 3 better but more expensive.

What type of memory ,I know this board supports pc133 but is it DDR compatible.

Motherboard does not support DDR, pc133 is fine.

I would gowith the Geforce2 Pro instead of the MX for the vid card. Much higher performance and not a great deal more expensive.
