Per recommendations from a previous Post, I changed my 5770 GPU to the 560. I am now experiencing stuttering graphics on opening screens and 0 FPS on some modded games. I never had that problem with the previous card.
did you go into the control panel and uninstall the previous drivers ?
did you do a custom install when you installed the nvidia drivers ? there could be driver issues, some relating to sound because both parties install sound through HDMI drivers if you just do an express install.
Nvidia actually recommends a 520w power supply for a system with a GTX 560. This assumes a generic power supply and you would be fine with a high quality 450w unit but what is the make and model of what you have now?
Tried uninstall and reinstall per your recommendations--no joy, still stutters.
The power supply brand is Antec.
It seems the problem is worst playing Starcraft 2 at recommended ultra settings, the computer actually shut down twice when a lot of action takes place on the screen. Reducing the setting the still gets me warning messsages about " slowing down the game"
