Although Virtual DJ is demanding in CPU power, both CPU should be able to handle it very well. The A6 might be a tad faster because it is quad core and virtual dj support multiple cores but this is negligeable, just as the i3-2330m would be negligeably faster in day to day Microsoft Office.
You won't have any problems playing web based games with both processors. Age of Empires 2 is playable with both cpu's although the a6 would offer more frames per second in a once again negligeable manner considering that AOE2 is old.
Other components would make the difference. If there are no difference, choose the cheapest.
