One other thing I found can make a big difference, when dealing with
higher resolution playback, IE 1080i/p, is a card with faster RAM, IE
GDDR2 or GDDR3. I have two identically GPU'd cards, a 5500 and a
5700ultra. Even when clocked at the same GPU clock, in the same
machine, the 5500 tears at 1080 and the 5700 ultra doesn't.
The 5500 has a 400mhz memory clock and DDR1, while the 5700ultra has a
memory clock of 500mhz memory clock, and DDR2.
Just one more thing to factor in.
