If it were me, I would chose the iMac over the towers any day. I work at a design firm that has 20 iMacs and we've never had an issue with them. The Mac Pros are way too overpriced for what you get. Yes, I know you can expand them, but really all you can do is switch out a video card or add some internal hard drives. Unless you're doing 3D or Video editing and have to have the latest video card, then the iMacs are more than capable machines. The only issue I've noticed with the newer LED screens is that if you're not looking straight at them, the color tends to change. It's fine when you're at your desk, but if you walk over to someone else's desk and try to look at something on screen while standing, it won't look quite right to you.
As for the processor..the Core i7 is a much newer chip than the Core 2, and even though they have a lower clock speed will run circles around the higher clocked Core 2. If you do a lot of Photoshop, it's written to use those multiple cores, so you will benefit from it.
