Thanks uncfan_2563. I'll take your word on the performance of the card. However, my son plays WOW 36 hours/week. That's almost as many hours as I put in at work. Seems more than occasional play, but I won't push the point.
<I used to play 30 hours/week, so I have little room to be critical>
Bottm line, is the configuration I've describe adequate in your judgment for "great" WOW play?
