Here's another one of these threads: buying a MBP and so torn on the options. Very confused on dual core vs. quad core. I've done a lot of reading before posting this but I'm still confused so figure I'll just ask. Going to be doing lots of music production on GarageBand/Logic- here is the MBP I found: -Late 2010 or Early 2011 model - Intel i7 2.6 GHz Processor w/3.2 Ghz TurboBoost (PRETTY SURE IT'S DUAL CORE) - 256GB Solid State Hard Drive (Is this critical for faster speeds?) - 8 GB of 1600Mhz DDR3 SDRAM - Upgraded 15.4-Inch Display to High Resolution Matte w/Antiglare - Dual Graphics Processor - GeForce GT 330M w/512MB VRAM $1500 I'm uncertain because of the hard drive size, the fact that it's not retina like the new ones, and more than anything because I'm pretty sure it's dual core. Any advice from the experts on here if this will work for music prod. and also if its a good deal? Thanks!
