I remember I had an older (2006) hp laptop that had nvidia on it. I installed Fedora Core on it, and luckily nvidia had linux drivers, you had to compile them, but they provided them.
Took me a while to get it to work correctly but I did. I have a computer right now that I would love to put linux on, but it has a nvidia card in it, screw that, 7 it is.
Thats what sucks. Its takes a long time to get used to but once you do linux becomes the best OS out there. Love the fact that ssh is built into terminal (unlike windows).
