Im in a situation where I can sell my P4 2.53 for 170 dollars. I can also buy a P4 2.4 800FSB on newegg for 170 dollars shipped. Will I have better preformance if I run the 2.4 in my Asus P4T533 with the Rambus at a 3x instead of 4x and the FSB as high as it will run? I know it wont be 2.533 ghz, but it wil be ~ 2200-2400Mhz with HT enabled. Its basicly free, will I regret the trade?
