well im wondering what exactly is needed to add a separate graphics card and disable the integrated? What kind of cards could i connect on this computer? http://www.costco.com/Browse/Product.aspx?Prodid=114975...|84|56671&N=4017755%205000014&Mo=4&No=4&Nr=P_CatalogName:BC&Ns=P_Price|1||P_SignDesc1&lang=en-US&Sp=C&topnav=
Since after doing a little research, im assuming that u can add it via a PCI space... so heres the expandability it lists:
* 2 x 5.25" external (1 occupied)
* 2 x 3.5" external (1 occupied)
* 4 x 3.5" internal (1 occupied)
* 1 x PCIe x16
* 1 x PCIe x1
* 2 x PCI
Technically, anything. I would think it pointless going past a radeon 4870 with only an Athlon IIx2 though. I can't find any details on the power supply though. you will want to make sure you have enough power. And a 6-pin or two if needed.
You will add it via the PCI express (PCIe) not the PCI. Oh dear god in heaven not the slow PCI.
To "disable" the integrated, plug the screen into the new graphics card, rather than into the integrated.
If you want us to help you choose a graphics card, give us your pricerange and what you will be using it for. They range from $30 to $700.
