Do to the fact my motherboard only supports PCI, I am stuck with a small variety of graphics cards. Regardless, I have a question. I currently have a PNY GeForce FX 5200 PCI 128MB, but I recently found a site that has a Inno3D GeForce FX 5600 PCI 256MB. I've searched and searched for reviews, but failed. I was wondering, is it worth upgrading to this graphics card, or will I not see that much of a performance boost?
