Hi there, I have an Asus F5N which came preinstalled with Vista Premium and it was slooooooow, I have downgraded it to xp and miss the features of vista an i can easily upgrade ram but my 2.2GHz Single Core AMD Turion 64 I feel could do with being replaced with a better one and my 128mb Graphics Memory i feel is poor aswell, however i have not heard of Upgrading the CPU and GPU's on Laptops, and I am asking if it is possible, thanks, Josh
