Hey I have a Dell 4600 and my old ATI RADEON 128 AGP card the graphics was getting screwy so I went ahead and upgraded and bought a ATI RADEON X1300xt 256 AGP 8X and everything is installed but I am not getting picture to my monitor and I don't know why.....the other specs for the other graphics car I don't know it came with the computer when I bought it...
