I recently got a 5970 black edition via ebay from a seller who claimed the card is brand new. I've been putting the card through it's paces and realized it occasionally has glitches in several games, some avatars might develop a permanent fidgeting in game, some games with really low graphics requirements run at less than decent speeds and I've begun to wonder if it's games i'm playing or the card, is there any type of program I could use that could put the card through the paces and give me an answer ?
