GRAPHIC card advise

[c_rich]

hey all, got some quick questions.
looking to upgrade my graphics card but im running into some problems. the problem is i have no idea what im doing. Im looking into getting a NVIDIA Geforce 8800 card but im not sure if my comp is compatible. i believe i have an integrated graphics card so im not sure if that means im able to upgrade it or not. i also understand that my power input has some affect on what i can and cannot do.

If it has a pcie slot on the Mobo then you can put any pcie graphics card in. This will take over from the on board graphics usually automatically.

As far as power is concerned you need to know first what the output of your current unit is. To do this you need to open the case and look at the stickers on the power supply unit. You might see something like 300w or 450w depending on what you have.

Report this figure back and we can advise from there.
