I'm looking to build something in a mid tower case, 2 gigs of ram. Is it better to run a raid array or a 10K rpm drive for the OS and games? I will be mainly gaming with this. I don't need a monitor or any of the other peripheral stuff. I'm leaning towards a C2D 6600. With an X1900XT 512mg Sapphire card. I've looked on newegg for about 3 months but now I'm mainly looking for opinions.
