I'm going to be purchasing a 12" powerbook soon but I'm not sure whether to get the 1gHz model for $1100 or the 1.33gHz for $1400 with student discount. I will be upping the RAM to 768 on my own and either putting in a 7200rpm internal drive or going for an external firewire drive. I have been looking for benchmarks to compare the two machines but have not been very successful. Searched the forums, found very little. I don't really play games but I do alot of audio stuff. So I'm pretty much asking, is the extra 330mHz worth $300? Money is VERY tight for me so it really has to be something in order to convince me to go big. Any links to benchmark info or personal experience would be apreciated.
