No I realy dont OC. I dont need a heat engine in my house... its sooo hot already. And yes everything is setup for AMD, so ddr2 is included. And the reason I wanted to go x1900xtx is because I want to play oblivion at 1280x1084 with no questions asked. My current card supports Shader 3.0 which slows the game down too much.
No, I dont represent Comptia, or any exam standerdizers.
I will look at the x1800 though. Which maker has the fastest card?
