Hi all. Im looking to upgrade to a non intergrated graphics card on my Desktop. Intel I5 2.8ghz, 6gb ram, currently has intel graphics family. I dont have much experience when it comes to a computer upgrades. I can currently do a, somewhat dual monitor setup via HDMI on a HDTV, so I would like to still be able to do that too, or even dual monitor with a monitor, but not neccessary.I also edit videos, so theres that too. I dont need cutting edge, but I would like something that will play current games easily. I have a Gateway DX4850, if that makes it easier. I can seem to figure out if I have PCI or PCI express. I tried a program called CPU-Z, but the graphic interface is all grayed out, so I have no idea
