I know there are quite a few posts here regarding this topic, but nothing really fits my use of the computer. I am a graduate student in chemistry and I use my computer to do a lot of data processing and manipulations (ie huge spreadsheets of data). I also use graphical analysis software to plot and analyze the data. These processes seem to be pretty CPU intensive, but I am still not sure if it is worth the upgrade to the i7. Also, I plan on using parallels or something similar to do simple calculations using PC software. Is the i7 worth it? Thanks for your help!

    LOL, so there you have it. OP asks for opinons and gets them leaving him right back where he started!

     

    However to the OP please go to your local Apple Store and try out a machine there, then determine for yourself.

    27 in iMacs newest models allow RAM update later by the user.

     

    21 in iMacs newest models do *not* allow RAM update later by the user.  If you have spare dollars, and if rkaufmann87 thinks you need it, pay for more RAM now.

    rkaufmann87, I have played with them at the store, but it is difficult to get a feel for their speed while processing data.

    Then that leaves me to believe CPU installed on the store's machine was perfectly adequate. When you say processing data that is a VERY general term. What apps do you intend to run and exactly what type of dp do you intend to do?

    The Excel work is very lightweight so I wouldn't be too concerned. Prism should not be a problem either, Displaying 3D models isn't terribly difficult either however if you animate the 3D models while manipulating them that could be taxing. I have to say though I'd probably get a 27" (I know about the desk, just get a new one!), upgrade the RAM to 24GB and use an i5. If you can't fit a new desk or have some other reason for the 21.5" model then I'd get a Fusion Drive, i7 CPU and max out the RAM to 16GB.
