My wife, as a Graphic designer, uses her Macbook Pro (Intel 2.16 Intel C2D and 2Gb ram) for all her work. Lately her computer has been a little slow and the fan running at full speeds most of the time (graphic design applications demand cpu load). I was wondering if I could rather buy some parts for my old desktop and have her use that instead, running XP and Tiger in dual boot. The desktop is a Intel C2D 2.4Ghz with 2Gb ram and a Ati X1300 praphics card. The parts aren´t much better than the laptops, but will they run the OS better? Shouldn´t a desktop with the same specs as a laptop run faster?
