Ok this is a dumb question but here goes, lets say you have a slow computer, say 560 Hgz would putting a video card in it speed things up or slow things down?
My first guess would be since the video card is handling all the display properties and such that would take a load off of the slow processor, then I though would it or would the processor have to handle running the video card? I mostly ask because my moms pc, very old I know but it's all she has, is like this and I wanted to add a video card to it, for 1 to try and speed it up even a little bit, and for 2, well we got rid of our cable and she wants to hook her computer into the tv to watch her favorite shows that way over the internet, but her motherboard doesn't have a slot (AGP?) for the video card and I heard PCI cards are not very good, not to mention old and likely hard to find.
Sorry for all the questions, this video card stuff just doesn't make any sense to me.
