    Hi! I'm in college and bought my first iMac a while ago and my parents fell in love with it and want to get one. I found a refurb in apple's store with a 6970m and compared it to the new one with a 660m. Which is the more powerful iMac. The 2011 model can be had for 1599 and the other 1799. Thanks.

    The 2011 iMac with 6970M is more powerful than 2012 iMac with 660M. With that said, I had a bad experience with pre 2012 iMac, which kinda hot to touch when under heavy loads.
    And this heat also leads to some hardware failures which makes Apple replace the whole unit instead.

    That's not necessarily would apply to you, though. But it's a risk you need to consider when making the purchase

    Warranty?

    If they give you the proper warranty, i would go with the 2011 model it has a cd/dvd rom, it is faster, and it also supports 32 gig ram.

    If you use Adobe products, or do any photo/video editing you will probably get better performance from the 660M.

    Agree with him nvidia has more support and it runs really really cool. Most people dont need the i7 anyway.

    2011 model is probably faster and will save you money! Go for that!

    2011 model will be faster. CPU performance is comparable. The 6970m is about 20% faster than the 660m and has 1 GB vram vs 512 MB of the 660m (which is weak for the resolution).

    So surely the 2011 model is better, no?

    Yep it's faster, but it also runs hotter. Oh yes I've been there so I know what 2011 iMac feels like when it under loads.

    I got my 2011 replaced and get a 2012 iMac, it seems to be a better machine, better cooling, not as hot under heavy loads .. and as much as I hate myself being hypocrite, the slimmed down, redesigned iMac is growing on me.

    I'm not sure if anyone is actually looking into the specific processors in these models. So, I thought I'd help.

    2011 iMac 3.1GHz i5 (2400) Benchmark = 5838
    2012 iMac 2.9GHz i5 (3470S) Benchmark = 6354

    Looks like the 2012 will be faster when it comes to just CPU.

    6970M is a little faster than the 660M when looking at benchmarks, but it depends on what apps you're using and if those apps utilize Nvidia's CUDA

    GPU wise yep, sorry that was a typo. the 2012 model is better cpu wise but is it worth $200 to you.

    http://www.anandtech.com/bench/Product/363?vs=702

    Difference is minimal when the 2400 is compared to the 3570S (comparison is to the 3.2 ghz 3470)
