I am deciding on weather getting the MBP with 8GB ram and a 720Gb HD, or one with a 500GB HD,and 4GB ram, the second one has a 2.7Ghz i7 dual core, but the first one has a 2.3 Ghz i5(Dual core). I could use the extra Ram as i like to virtualize, and like playing the sims 3... So what would be better the faster processor or the 8GB ram?, this is going to be my first mac, i have used them and i love them, and i can't afford to buy a new one each few years, so i need to future-proof this one.. , and i realise that i am going to be forced to use intels "Awesome" integrated graphics.
