I have an Intel P4 IBM Thinkcentre PC, 2005 model. It has 1GB RAM, 80GB HDD & its clock speed is 2.66GHz. My OS is Win XP SP3. It does not have a graphics card. Is it possible to install a graphics card to this configuration as many latest games don't work with the existing configuration ?
1. Does the motherboard have a socket for the graphics card? Many boards with integrated video do not.
2. If it has one, what kind is it (AGP or PCIe)?
3. Does any video card that fits the board fit your budget?
Definitely open the case up and look to the lower middle section of the motherboard. Most motherboards have their ports labeled fairly well. Look for pci x16, pci x8, or possible agp in text. AGP is worst case scenario, that means you'll be stuck with a decent at best video card unless you buy a new motherboard.
You may need a better power supply also, the wattage of the power supply can usually be found labeled on it somewhere.
