Thanks everyone, just the info I finally need!
mwell, you're from England?
Yippe, good thing I didn't upgrade to 8GB RAM. Didn't really know CS4 can only utilize 4GB RAM max. There are all sorts of people out there advising to upgrade to 8GB or max out the RAM capacity!
And thanks guys, for telling me not to buy RAM from Apple directly. I didn't know Mac uses the same kind of RAM as PC. Yeah, when I saw the prices of the RAMs they are selling, I thought, they were simply crazy. Even their hard disk upgrade is crazy. For 1TB more, we have to pay like S$350 more?!!
mynameisgreg: Thanks, yes, I read from somewhere on the net that going from 4GB to 8GB has diminished returns. That was what confused me. Cos some other guys recommended going for higher RAMs to improve performance.
So think I might just stick with i5 with 4GB RAM. Sounds good. Thanks once again guys!
