Hi I'm looking to add just one thing to my old pc to optimize it / speed it up a little bit when opening up documents or for the most part surfing the net. I don't use the old PC for anything else but surfing the net. I have already maxed the RAM but if you had to pick one, which would you add to an old PC with Windows XP and only 20GB hard drive and 256MB RAM (already maxed out)....a 2nd bigger hard drive (say 40GB more or 80GB more) or a video card with 128MB or 256MB memory? I have been told both can help but which one would you root for in this situation? Again, I wouldn't be using this PC much for anything but surfing the net...as it is today it takes quite some time for the browser to open up, etc.
