HD 8670m .....disappointed.........

[minotaur2]

i wanted a gaming laptop and i heard that hd7670m offers acceptable performance according to notebookcheck it can run borderland2 40fps on medium and crysis2 30fps on high which is enough for me so i went for an acer with core i5 4 giga ram and hd8670m which has similar name to hd7670m and i assumed it will do better i was wrong now games are lagging and i can't get 23fps in borderland 2 on medium , is there any way to improve this graphic card performance ??

Hi update:

Is it possible that poor performance because the game is using the integrated intel GPU instead of AMD one and how to force the game to use the AMD graphic i found no option in bios for that any help is appreciated .
