    Is $180 worth it to upgrade the base 27" iMac to the i5 processor? This is not the quad core. I thought the turbo charge might help me -- I am going to be commuting to a school for engineering and would like to work on projects using AutoCAD for Mac when I am at home -- but I am also on a budget.

    It would be ~$1700 vs ~$1900...the quad core is ~$2000 but with tax might be more.

    Thanks!

    if it were up to me i don't think the i3 to i5 would be enough of an upgrade to justify 200 bucks

    if it were from an i3 to i5 quad core i believe you would notice more a difference..

    an basic i3 will be able to handle autoCAD just fine, its the graphics that will bottleneck before the processor on an application like that.

    Thanks for your input! Given what you said, would upgrading the video card be a better idea? It would be $150 to go from an ATI Radeon HD 5670 512MB GDDR3 SDRAM to ATI Radeon HD 5750 1GB GDDR5 SDRAM.

    I will definitely buy RAM aftermarket, as I did for my 2007 MacBook that has 4GB and is still working pretty well. Up to 16 GB will be nice :D

    Why not get a refurb? i7 goes for as low as 1699$ and will beat both of the Macs you listed.

    Uh, no!

    The Quad Core i5 is $1,699 in the Refurb store. I just bought one. Delivered this past Monday.

    The Quad Core i7 is $1,899 in the Refurb store.

    The previous gen i7 used to be 1699$. Looks like it's not in stock at the moment

    In about 3 weeks Intel is going to release Sandy bridge and the Core series will be slow in comparison. This is a bad time to spend money on any computer with a Core series CPU. Wait for the next imac update or you'll regret it.
