According to the notebookforums, my E1705 (purchased February 2006) is upgradable to a T7500 plus a 7950GTX video card. In the original thread I made on the site, the guy suggested I go with a T7200 and get an very specific oem fan. The original thread starter talked about AS5 or something like that, alongside with saying that the upgraded video card should just plop in. Anyone have experience with this? Is this relatively easy to do? I don't want to take my computer apart only to break something.
