I recently bought a HP (Hewlett-Packard) Pavilion Media Center TV M8200n Desktop
(3GHz Athlon 64 X2 6000+, 3GB DDR2, 500GB, DVD±RW DL, Windows Vista Home Premium - MPN: GN551AA)
It comes with an integrated NVIDIA GeForce 6150 SE. I want to change this to a new dedicated video card. There is a PCI-Express x16 Expansion slot, so my question is this. Is it as simple as uninstalling the integrated GPU's drivers, then installing a new video card like normal, including a new power supply if needed (most likely) or, because it has an integrated card in it, will it be more complicated? Is there something I should know?
This computer is for my wife, who loves gaming so any help would be greatly appreciated.
