I have an inspiron 530S Desktop. I am running windows 7 on it. I have 3 gigs of memory. I went and purchased a Nvidia GEFORCE 8400GS GRAPHICS CARD. It is 512MB DDR2 PCI. I would like to install it on this computer I just purchased. Can I install this particular Video Grapichs Card in this particular computer? If so where is the location where I need to install it. I gave a good bit of money for this and I hate to just put it on a shelf and never use it. Any help wopuld greatly be appreciated.
