My first computer had an ATI card which had the most wonderfull habit of crashing every 5-20 minutes, no matter what I was playing. I swear, I haven't had as many crashes in the three years since I switched to Nvidia as I used to have in one day with that card.
haha..I don't doubt it..I purchased one of those ATI video capture card's (el cheapo), man that thing could crash ANY OS!
