I'm new to Photoshop and planning on purchasing the education discount version with a new MacBook Pro 2.26GHz. I plan on upgrading the memory to 4GB and the hardrive to 360GB @ 7200rpm. Is the 2.56GHz processor worth the extra $300? I know the memory and hardrive will be about $140 if I get the 2.26GHz version. Will I notice a big difference between the 2.56GHz and the 2.26GHz?
