I will be attending a four year college come fall, and i would like to have some opinions on whether it would be better to get the new 2ghz 20inch iMac for US$1699(including apple care plan) or the dual 1.8ghz powermac for US$1499 (not including apple care plan or display). The drawback with the Powermac ofcourse is the fact that it only has an 80 gb hard drive and i would also need to purchase an additional display. Also, the old powermac only has 64 mb of vram, the new imac has 128mb . I will be using the computer for research and word processing, but would also like to be able to edit video & play games occasionally. Also, does anyone know if the 100$ off promo for educational purchases also applies to the old powermac? (it applies to the Imac, making its actual cost 1599) Thanks for your help.
