Hey guys new to this forum, so anyone's help will be greatly appreciated. I'm switching to mac from pc because obviously windows is garbage. Im looking at buying an imac either a refurbished or new. I'm mostly trying to decide between the i3 or core 2 duo. Prices are in Canadian dollars and are about $300.00 dollars difference between the two.

4GB memory
500GB hard drive

$1.299
New imac 21.5-inch: 3.06GHz Intel Core i3
4GB memory
500GB hard drive
8x SuperDrive (DVD±R DL/DVD±RW/CD-RW)

Thanks for anyone's help.

It usually depends on your usage, but in this case I'd just say get the i3 model. For 200usd more you get a slightly better cpu but a way better gpu.

Thanks a couple other people have told me that as well, that the gpu makes it worth getting the newer one.

Thanks for your help.
