Well, I have always used ATI exclusively. I am very brand loyal; like how I only drive Fords. However, this is the 3rd ATI card in a row that has given me issues. I'm considering a change. I've never been an Nvidia fan, but I'm sick of my screen freezing and the computer rebooting. My wife works from home on this computer, so she's not the happiest of campers when it does it's magic in the middle of her work.
EDIT: Just a note that this particular go around my video card is on the board (the other two times were actual cards). It does not have a fan and shares memory out of the board RAM (both against my usual rules). This might be why, but it's still irritating as hell. And by the way, it is choppy with intense movement.....which has been a sore spot as well. Anyone else experience this with the Raedon HD series?
