5870 seems to run ok . AAX4 AFX16 1920x1080 . All SH5 graphic settings set to max . All options ticked except vertical sync .
I have noticed that if i put the card in control panel to optimal settings , the picture will be better and i get around 35fps average . If i put the standard settings to high quality and then bump the aa up 4x and af up to 16x and leave the other settings then i get around 120 fps average .
