I'm proud to report that my pc is still at 3.4ghz and no issues. LOL....still using the same stock hsf and low end memory. Unlike most of you, I have saved even more $$$ by keeping stock cooling and cheap memory.
Last year I was using an Shuttle XPC small form factor with an amd XP 2400+ mobile cpu. I had that puppy at 2.3ghz(from 1.8) and I couldn't believe it since the shuttle case has a 250w ps with limited airflow. Anyway, I sold that puppy to a sucker and got $450(it was in perfect condition). That basically paid for half of my current setup excluding the 32" and dlp tv...and 500g hd.
