But when I render with HANDBRAKE the machine with more cores at same or higher CPU speed has won everytime.
BOTH WORK. The i7 should be the faster of the 2 if the other parts of the machine are equal.
I'm about to buy a Imac, mainly for video editing, but I don't know what to choose between an i7 3.4GHz or a quad-core i5 2.9GHz with a 1G graphic card. Please help...
