My five year old MSI socket 478 is in the process of eating shit. I need a mATX mobo on the cheap(<$100). I just transfered into Computer Science at school and would prefer if Linux also ran on it. Up until now Ive only been looking at agp boards, but but my gfx card prolly also could use and upgrade. Since i dont have an excess of cash im leaning toward an AMD, even the $185 C2D is above my spending limit. Any recommendations on brands or pci-e vs agp would be appreciated.
