OpenGL is pretty agnostic when it comes to video cards. I use mostly NVIDIA stuff (GeForce 4FX on the main PC, Geforce2Go on the laptop) except for my Macintosh, where an ATI Radeon 8500 (originally PC, flashed the BIOS for Mac) works admirably under Quartz Extreme (Apple's OpenGL environment, I think.) Shouldn;t matter either way. /P
