My friend is on a Compaq Presario SR1711Nx, and he wants a new video card. He's got an AMD Sempron (P) 3400+ 2.0ghz processor, 512mb ram. I looked up his mobo, he's got a pci-e slot, and a pci slot. I'm not sure what video cards would fit, also what his power supply could handle. I don't know his power supply and neither does he. Is an upgrade on the video card possible? (Current one is integrated pos). If it is, what is the best he can upgrade to without upgrading the power supply, with power supply, and reccomendations of what to upgrade?
