Hey guys, I'm by no means new to Apple, which is why I'm asking this. I just bought a new 27" iMac 3.1GHz quad core with 8GB of DDR3 RAM. There is barely anything on its 1TB hard drive. This is the newest and most powerful stock iMac. I use it for work as a graphic designer - meaning I use Adobe CS 5.5 products. The problem is that when using these programs, manipulating images, text boxes etc is terribly slow and choppy. This is not the case with my older iMac or the crappy Toshiba tiptop I've had to deal with up until this point. In fact, the 2GHz duo core Windows XP machine is easily outperforming my new iMac. I know this is wrong and I can't figure out what the problem is... so, any ideas?
