Hi I have MacBook 2.2 120GB hard drive 1GB Ram super drive . I want a fast desktop computer because i want a big screen and a good graphics card. So have been looking at refurbished iMacs at apple's website. I dont know weather to get a 20in iMac (aluminum) with a 320GB HD, 256MB graphics card, 1GB Ram, 2.4 processor $1099. Or the 24 iMac (white the older ones) with a 250GB HD, 128MB graphics card, 1GB Ram, 2.16 processor $1199. On the iMac I will be using it for internet, a little Video editing, a little gaming, and other things too. Also I am keeping the macbook too. Thanks for helping.
