I have an old Pentium 75 MHz computer that I still use frequently. I was wondering if getting an extremely cheap video card that supports OpenGL would be worth it? I would not be playing any games, but I would be doing some introductory programming for OpenGL on the machine. I currently have a S3 Trio64 in the computer and wanted to "upgrade" to a used card like the Voodoo 3 PCI or ATI Rage 128 PCI, not for the intent of gaming, but for the intent of introductory programming. Thank you for your time.
