Doesn't the G2590PX suffer from ghosting\blurry when used with an nvidia GPU?

Where did you read that?  Read the Responsiveness section of PC Monitors review.  Unlocking the color controls (set Game Mode To Off) slows the pixel response times down slightly, however this is not important unless one is going to calibrate (requires a colorimeter) or play with the settings since the monitor is very accurate out of the box.
