Not necessarily "stuck" but I am debating which upgrades to get. I can't decide whether or not 2.0 GHz quad core is enough juice or not. I know I will be upgrading the RAM to 16gb, what do you guys think of the CPU though? Would I need the 2.3 upgrade for the $100? Hard drive size is no big deal. I can store things on externals if they are taking too much memory. Main uses: Photoshop/Illustrator Ruby and Wordpress Web development Occasional windows use with Bootcamp Surfing, etc. Just don't have much experience with quad core. I have a quad core 2.7 ghz processor, and I find it pretty speedy, in my 2011 imac, but it's an i5, not and i7. I'm also running 24gb of ram on the iMac (rmbp would be 16gb) Am I going to notice a speed reduction if I go with the 2.0 quad core i7 rMbp?
