Hello everybody! I'm Jonas, and i have a refurb 15'' macbook from 2010. I'm living in Hong Kong for the next month, where the mac computers are 400€ cheaper then my hometown in the Netherlands! I'm thinking about upgrading. I study to be a car designer, so I need to be able to have some processing power. My 2010 mac always did just fine, I used to have a windows partition with Solidworks (very heavy 3d program) on it, but now it can't really handle it anymore. Photoshop and another graphic program at the same time is OK now, but not fast. I don't edit video, just draw digitally with a wacom. This is my 'ABOUT' page of the current computer. MacBook Pro (15-inch, Mid 2010) Processor: 2,4 GHz Intel Core i5 Memory: 8 GB 1067 MHz DDR3 Graphics: NVIDIA GeForce GT 330M 256 MB With a spinning harddisk with 320GB, and 106GB free. All i changed about this computer is that I put extra ram in it. To the point: what notebook can i buy that will stay most up-to-date (in speed) for the next 5 years? Will it be really much faster then my current computer? (I don't care about display size or quality, I have an external display at home. Portability is a plus) 13'' macbook pro - What makes a mac fast? The fact if it's i5 or i7? - Does 1tb or 500gb make a difference for speed? - Can i put in RAM from a 3d party? - Is the 15'' one faster? macbook air maxed out - Could this be a option? It has i7 and 8gb ram! The new macbook - Will it have processing power? Thank you for reading this, i hope my question is a bit clear!
