Hi all, I've got my new 27" i7 iMac w/ 4GB RAM, and a 2 TB HDD. I've downgraded from an 08 Mac Pro (octocore @ 3.0GHz, 18GB 800MHz RAM, GTX 285, Intel X25-M G2 160GB SSD). I'm wondering if the speed I'm experiencing is normal? It's not application load times that I'm thinking are slow (that's expected going from SSD to HDD), but just like switching tabs in Safari often I get the spinning wheel, it never used to happen except on very rare occasions. Even changing panes in System Preferences is slower? Is that normal?
