I'm planning to buy a G5 soon but I'm not sure which model to get. I was leaning towards the 1.8 at first but now I have second thoughts. I don't want to get the 1.8 now and later regret that I didn't get the 2.0 instead. My budget right now is kinda tight and I really need a new computer, My G3 iBook is killing me. I'm a graphic design graduate, what would u recommend? Thanks.
