In the case of the OP yes a dual core will be sufficient for his use but the discussion blossomed further then the original question. As has been said thos of us with quads used to have dual core and therefore we know how much different our systems are because of having a quad core so if we say it is more responsive (not load) then we have obviously found that to be the case. Unless the suggestion is that werre all intel\amd employee's attempting to convert the masses i really don't see what the problem is in understanding that we have found our systems more responsive. I really do think some people just come on forums looking to have an argument and it doesn't matter what it is as long as they can argue.
