Hello all,

I recently acquired a stock XPS 420 with a Core2Quad P6600 off of marketplace and I would like to upgrade the CPU. My idea is to dual boot Windows XP to run legacy games and programs and Windows 10 for fun while it still can.

Someone else near me is selling a Core2Quad P9450 for cheap, will it work with this computer? If not, what is the most modern processor that I can install?
