i have a intel celeron 2.6 cpu size is 478 ( came from a dell dimension 2400) wanna replace the board so i can install a graphics card. im kinda dumb to the hardware part though. when i look for boards there all lets say, p4 cards or presscott? that really makes no since to me. do i have to get a board where the specs say celeron or will a p4 board work or what. trying to get a pci-express board for a pci-express video card (from what im told thats better than agp right?) so i can hook up and use my hdtv as a monitor with the dvi slots with a crisp picture. I know its a stupid question and believe me i've been doing my research, thats the only thing that doesn't make since to me. thanks guys in advance
