Now I will also agree that your question is mute, most PCs come with an integrated graphics card and most motherboards have a PCI-e slot or regular PCI slot where you can install your own graphics card....so search the net for that PC and see if find out if the motherboard has an extra slot for graphics.he integrated graphics chip on the new will be far faster than what you have in your old PC. If you are unhappy with the performance of the new PC you may always add a graphics card later. If the integrated graphics uses 256 meg of the PCs memory make sure the new PC has at least, preferably 4 or more gig.
