    Hi there!

    I'm going to purchase an iMac for my younger brother. But since I've spent a lot of money for my own custom-spec'd iMac, I can only handle the baseline one. Since my brother will play some games like d3, sc2 and lol, there's some need in the information about the specs of 640m that is currently in the iMac (clocks, bus width etc.), not the theoretical one.

    So please, could some of you guys run a GPU-Z under the bootcamp and post the screenshot of it here?

    Would really appreciate that.

    The 650m is about 30-40% faster than the 640m. The 650m gets around 50-60fps in bootcamp in Diablo III with everything max on the 21.5. If I were you I would look into buying refurbished. I purchased my last iMac (2011) refurbished and it is no different than a new one, same warranty and everything, straight from Apple.

    You can get the higher end model with a 650m, refurbished for a great price.

    Thanks for response, but I'm in Russia and am not able to buy refurb'd one.
    I do know the level of performance of 650m since I have one myself =)
    So noone with the 640m and Bootcamp?

    I've got the a base 2011 model and it plays games on mid-high without a hiccup. Even in Mac OSX. I do play on bootcamp though, and also pay LoL, D3 and Guild Wars 2. I don't have the settings maxed, however Med-High I get a solid 40-50 fps. It isn't a beast of a machine, but at the moment, it more than for fills my needs.

    Thanks for the answer.
    However, I specifically asked about 640m from the late 2012 iMacs. I simply want to know if there's something that will prevent me from overclocking it to 650m-660m's clocks.

    I have the base 2012 model with the 640m graphics card. The only games I have played are the Sims 3 and GTA San Andreas, both run great!

    Imac 640M gaming

    Hi everyone, first time post,

    I see nobody answer this so here is what I get from my Imac 640m entry model:

    Crysis 3 1600 x 1080 - all low only lents flares = 35 FPS absolutely playable
    F1 2012 1600 x 1080 - all high only shadows and ambient occlusion low = 55 FPS
    Dirt 3 1600 x 1080 - all high only shadows and ambient occlusion medium = 58 FPS
    Mass Effect 3 1600 x 1080 - all high = 60 FPS
    Starcraft 2 1600 x 1080 - all high = 55 FPS
    Metro Last Light 1600 x 1080 - all low = 37 FPS

    To me all the games looks way better than the Xbox 360 version, and I gonna replace this iMac when a new one comes (I'm not sure if the GTX 680M will handler the new games coming with the arrive of the next gen consoles) so I skip to buy the 27'' this time.

    I think that If you want to play some AAA games and don't care to much about visuals, the Imac with 640m will fits your needs for 1 1/2 year at least.

    Hope this helps to someone who don't know what to buy.

    (And sorry about my english).
