So, I need some help making a decision. I need to replace my loyal powerbook 15 that has been with me the last 4 years, because it can't cope with the load imposed on him by multitracking recordings in cubase with some plugins (as soons as I put reverb and compression on the tracks, it begins to suffer). I'm being offered the last of the silver macbook pros 17", 2,6 GHz, 4 Gb RAM, 200 HDD 7200 rpm, nVidia 8600 512 Mb. It is exactly one year old (the guy has the invoice) at $1.200.000 Chilean pesos (USD$2.180 aprox.). I love the keyboard in those macbooks as it is the same as in my powerbook. I have a MacBook Air so I tried the chiclet keyboard, but although I'm getting used to it, I still prefer the old one. The new MacBook 17 in Chile is $1.800.000 (USD$3.250 aprox, including taxes). For the price of the old 17 I'm being offered, I could get the base MacBook Pro 15" with nVidia 9400. Is the nVidia 8600 so bad? What do you think?
