Hi! I hope this is the right forum to ask this on, as I am debating before I buy an iMac. Basically, I'm in the market for a 20" iMac, but the processor difference has me confused. I'm wanting to know which would be better for me - a 2ghz processor or a 2.4ghz processor. There seems to be a huge price point difference and I want to know if the 2.4ghz is worth it. The most intensive program I will be using is Adobe Photoshop... the rest is just internet browsing. No gaming or anything like that. RAM will be upgraded to 4gb regardless of what I get, if that makes a difference... I'm really iMac stupid here as this will be my first apple machine, so I apologize if I come off as unintelligent! Anyway, any input would be appreciated! Thanks in advance!
