> What is the most critical computer component to crossfire RAM? CPU? Both? Crossfire typically consumes < 50M of RAM, so if you have more than that, RAM isn't your problem. However, if you don't have enough RAM, your CPU is irrelevant. I would: a) Make sure there's enough ram (probably 256 would be way more than needed.) b) Get a fast CPU. OR> c) Get the crossfire developers to waste less CPU power. I believe there are areas where we could get a factor of more than two. PeterM
