It looks like I may have to replace video card. (been thing about this for sometime). I currently have a GeForce GT 610. I will need to find a video card that uses PCI Express 2.0. I would like to find out, in dealing with outdated video cards what is someplace to go shopping. I have casually looked on Amazon and for this I do not want to use Ebay. More to the point where should I NOT go shopping. Who are the stay away from sites?
