I'm in the market to purchase a new portable Mac as I'm still using my 13" White Core Duo 2GHz MacBook with 2GB of RAM and the original integrated Intel graphics that Apple chose from three years ago. An average user may not have trouble with these specs. I am attending university in the fall, however, as a Fine Arts major with a concentration in Photography. I've got my eyes on the 13" MacBook Pro with 4GB of RAM (which I'd upgrade to 8GB after about a year or so) and a 2.53GHz Core 2 Duo processor. I only have a few concerns about the machine and I'm hoping that either a current unibody MacBook or a new 13" MacBook Pro user can help me out here... Will the 13" MBP be able to handle Photoshop CS3 and Aperture? I'll be needing these applications to edit my photos for college so this is important to me. I know the CPU is strong, but is the GPU strong enough for these apps? On Apple.com's Aperture page, the Nvidia 9400M GPU doesn't seem to be listed as a compatible chip. Also, this is not a life or death concern, but I'm just curious. Will Spore or The Sims 3 play on the 13" MacBook Pro's Nvidia 9400M GPU as well? I didn't see the chip listed under those compatibility specs either. Thanks to anyone with any input It's much appreciated!
