Great answers and this really makes me more confident in getting the i3 now and later upgrading to i5 or i7.
Now just to be safe I can also assume that the i3 will also have faster speeds on things like rendering videos in HD and recording gameplay.
now you are starting to ask the i3 to "bite off a lot and chew" where an i5 would be better suited.
(an FX-41xx won't be any better either)
part of the deal is what graphics card are you getting. i have a 550ti and in no way does it put more of a 50% load on my i3-2120 so i can do quite a bit of multi tasking while gaming. now if/when i get a 570 i would suppose my multi tasking abilities would hit some limitations while in game play.
