So I have an old Dell Dimension 3000 and I've decided that instead of simply letting it rot I'm going to connect it to a tv and use it for watching Youtube videos. I plan to upgrade the CPU from a Celeron D 320 to a Pentium 4 at 3.4GHz for $20 (Thank you eBay) but I can't find a graphics card that uses PCI. I know that was the standard forever ago but I thought there would be at least one or two floating around, and the motherboard doesn't have any PCIe slots. I don't know what an AGP slot looks like, so I wouldn't know if it has one. It was originally purchased in 2004, has 512MB of DDR1 RAM, and 76GB of space on a PATA hard drive.
