Should have similar gaming performance. While you have a "6850", I'm sure its the mobile version so it will perform more like a 5750 or your 5770. Doing CPU tasks will be much faster, but gaming over would be rather close.
Ja, its the mobile version. Its only 1 tier lower on the Toms hierarchy chart but I hoped that the better CPU and RAM would make a difference. I just hate stepping back in terms of GPU power but the laptop is such a great deal....
Thanks for the insight!
