Colours have gone from crisp and sharp to dull and dirty

my videocard a 4yr old Nvidia GTX 470 is getting approx. 3600, the latest cards are getting 7-9000 points by comparison the ATI 5450 ,which doesn't make that chart , though it is on top of the low-mid range card chart and gets 230 points....(yes 230 not 2300) the 5450 was 1st available in 2010 by the looks.... but maybe ok ,depends on the user and the budget of course.

the is the chart
