I'm really interested in getting a new iMac. The only thing is, I don't know which 20 inch to get. I would get the 24 inch, it won't fit on my desk becuase it is too high . So, I have to get the 20 inch, which is fine. My question is which processor to get? I have a 1.66 Ghz core 2 duo on my hp laptop now, wiht 2 GB of ram and it runs fine for what I do. If i get an imac, i will upgrade to 3 GB of ram. Do you think 2 GHZ will be good enough, or will 2.4 be better? Thank you for any help.
