What would you guys suggest to do? I guess this is a pretty comon issue to those purchasing a new MBP? I'm not very computersavvy when it comes to RAM though.. My question is threefold; 1) Paying 360 euro's to Apple to upgrade from 4gb to 8gb seems really expensive.. Is it cheaper and most importantly "better" to "do-it-yourself"? (I don't prefer a cheaper option if that implies getting less!) If so, where/how would you suggest to purchase it myself? 2) MBPs standardly come with 2x2gb (i.e. 4gb in total) of RAM. If you want to upgrade this to 8gb yourself, do you have to purchase 2 times 4gb, or does 1 time 4 gb suffice? (in other words, can you put 2 times 2gb PLUS 1 time 4gb in one MacBook Pro?? Or can you only fit a maximum of two modules (i.e. 2x4gb) in there??) 3) Finally, could I just take a 4gb RAM module out of my old (Windows)notebook and put it in a MacBook Pro? Or are there some requirements as to what RAM modules you can put in a MBP?
