What performance difference will I see between these two processors?

2nd one will be faster if you run newer games and stuff like photoshop and video editing. The first one will be faster for games like world of warcraft and games that were made up to 2 years after warcraft. First one is decent for regular stuff like photoshop but not as fast as the quad 2.33. The difference in their performance is very little except that the quad will outpace the duo on photoshoop and other software like that.
