ATI is in a good position still. With a price drop in their 8500, they can easily dominate the lower end market (under $200). And, they still have the advantage of dual display and beter DVD playback, which tops the Geforce3. With some driver updates, and perhaps a tweeked R200 chip, they can do quite well. When the R300 is released, we'll see what competition ATI can provide.
RAM Disk is not an instalation step.
