I do not see what Radeon card BirdDogICT uses. I am talking about Radeon HD, HD7870 to be precise.
I think you are correct here - in this thread, anyway, he doesn't say specifically. However, I am fairly certain he does use an AMD Radeon HD card. If I can find where, I'll post to show you. Again, I could be mistaken.
