I have overclocked both of amd processors and noticed a huge gain in performance I have water-cooling so heat isn’t an issue, My Amd 1700+ 1.47ghz to 2.2Ghz ' My AMD Barton 2500+ 1.8Ghz to 2.5Ghz and with my ram now running @ 250mhz instead of the default 166mhz I will never go back. My 1700 is more then 3 years old so im not to worried about it dying now. I must stress that these aren’t ordinary CPU's though. These where a specific batch that were well know to overclock well, The 1700 has the code dut3c which where high know to overclock massively , and my amd 2500 is a mobile model, know to overclock well and with out the heat issue as they require less volts to run then normal amd desktop CPU
