Well, I guess I have two weaknesses: (1) I do not like excessive amounts of fan noise, and (2) I hate having my computer being on the verge of burning up all the time. Reliability is important to me. Convenience too. Maybe I'm spoiled? I bought a Compaq because, according to their advertisements, they do extensive testing on their computers before they put them on the market. Unfortunately, there is a price to pay for that. Compaq is not quick to sell the absolute latest processor the minute it becomes available from Intel or AMD. [They do not overclock their processors, either.] The Compaq testing takes a lot of time. I understand that. As a retired electrical engineer, I spent MANY hours in a laboratory doing developmental testing of electronic hardware. It is not uncommon for equipment to fail in thermal or reliability tests. Without the tests, you are just asking for trouble. Overclocking sounds to me like an invitation to disaster. But there is another consideration, which may be the most important of all. That is "knowing what you are going to get before you pay out the money." I had hoped to find out what to expect here at CCC. That's why I ask about Kn/s and Fritzmark for my favorite software, Fritz. Maybe people have not had time yet to evaluate the new Fritz engine, so answers may be awhile in coming. Bob D. Bob D.
