VERY helpful post, thundering1!! Thank you!

I'm especially interested in this because I am going to have a computer custom-built. : ) From the sound of things, I am probably always going to have an issue with something -- because I want the comp for my 3D apps, but I would also love to be able to play the demanding games on it as well. :d

Ah well, my first choice is deffo gonna be to build a computer capable of maximizing the features of my 3D programs. Thanks again for your info, I never knew the difference between the cards. :D
