Re: How hard to upgrade video card?
It might be upgradeable. Of course, if it is... it will be incredibly expensive for a new one. Then, it will be incredibly expensive to get it installed (unless you do it yourself, which from experience I can tell you, is not fun). And finally, when it's all done, you wont notice much of a difference.
I went through all of the above with my inspiron 8600. Do yourself a favor and don't do it!!
