my question is ,what should be the MAXDOP settings in above case & why?
which will improve server performance.

Change the MaxDOP setting to 1 or 2 and see if you're gaining performance improvements. a value of 0 means a process can use all 8 processors. since all processes fight to get all 8 processors, there is a performance degradation. changing it to a lower value means processes will use lower number of CPUs and hence contention will be less.
