- Remember that an i7 in Windows class performs the same "end result" speed as an i5 in iMac class. Yes, different CPUs (that have different benchmark test restuls) but after adding virus scan progrms and other stuff on the Windows machine, the i7 is already bogged down (that makes it act as same speed as i5 iMac). Therefore, remember to compare against the specs of an i5 iMac (not i7 to i7 comparison). For stuff that I do with my iMac, the little i3 is same speed as my Windows i5 box. Do you really need an i7 iMac (for the tasks you do)?
I would like to see more than anecdotal evidence to support this. I am not sticking up for Windows, but I don't think this is the case in 7.
As for the original question... I look at it like this

$969 (+ 150 for not having Home Premium) + Dell UltraSharp U2711 27-inch Widescreen Monitor with PremierColor $1099 - sorry but it's the only 27" monitor from Dell that matches the iMac display
1198 + 1099 = $2291
vs

$2518 + 8 GB RAM from crucial / new egg / whatever ($40-$50) = $2568
The Dell monitor is not glossy (which is a positive for most)
The Radeon HD 6670 is a bit faster than the 6970M
The Dell HDD is smaller and there is no 2 TB option (check the prices of HDDs currently)
But hey, if it's on special, and it meets your needs, then get it.
In Summary:
Dell - $2291
iMac - $2568
Not using windows - priceless (nah, seriously - it's not too bad these days)
