PowerColor AX7770 $119.99
Somewhere around $100. Maybe a 6770? She says she may want to try Diablo III, will any of those suggestions work adequately? ...just as long as I won't be sleeping on the couch for a week or so
$109.99 after $10.00 rebate(s)
a little more than a 6770 but it performs "no couch sleeping" better.
