Alrite my friend has one of these computers i already told him to just build a whole new computer instead of upgrading this sony thing but he insists on just buying a better vid card. Anyways what he is wondering what kind of slot is on his mobo i think it maybe agp but im not to sure. Also he has 512mb ram what ram should he upgrade to ddr or ddr2? By the way the computer is about 3 years old.
