I've replaced my broken videocard Asus 9800GT Top with the following card: Sapphire HD7770 OC Edition. I switched the cards and then afterwards I removed the nvidia drivers (in the configuration screen) and installed the latest drivers for my new card.
Everything looked ok, but when i play Modern Warfare 3 for example, I notice that it doesn't run as smooth as with my Asus 9800GT, even when i reduce the advanced video settings.
What can be the cause or what can I do to fix this problem?
I was thinking to format my pc, but i'm afraid that the problem won't be solved.
Can there be a conflict with my old Nvidia drivers?
Is my system to weak for the HD7770 card (PCI-e 3.0)? Or is the 9800GT a better card (=256 bit)?
Can there be a conflict with my motherboard?
If someone can give me some solutions or answers...
I read a lot of things of driver conflicts when replacing a videocard from another type (AMD - Nvidia). But i find it odd that my "normal" activities on the pc such as Office, internet, mail, Photoshop,... runs smooth with the new card and when i play games the framerate is very poor.
