So Im in the market for a new MacBook Pro I have 2 options: New 13.3" MBP 2.53Ghz 'Old' 15.4" Unibody 2.4Ghz MacBook Pro Both in the UK will cost me ~ £1000 the first from Apple with student discount and the second off eBay. Which one should I go for? The 'old' 15.4" has a discreet GPU as well as the 9400M. The new 13.3" MBP has a 7hr battery and .13Ghz increase in processor speed as well as 4GB of DDR3 as opposed to 2. Also Ill get a free upgrade to SL in Sept (save p&p). Which one will preform better? I use office, the net, handbrake and Im a casual gamer. RA3 and Oblivion im playing at the moment. Like I said its casual, im not worried about getting high frame rates or maxing out the settings, just as long as it is smooth. Thanks for your help in advance.
