    Graphics Card Upgrade
    Howdie,

    I will soon be blessed with my first Mac;
    Apple iMac 3.06GHz w/ 27" Display MB952ll/A

    Unfortunately I was not able to configure one or get one with the 512 MB Radion HD 4670 graphics card.

    I really haven't played any games in over a year but when StarCraft 2 comes out in June, I do intend to play it from time to time.

    I'm a long-time PC gamer and although I've been "out of the game" for a while, I sure do apprecaite a good graphics card.

    Although it will run SC2 (but on pretty low settings), the 256 HD 4670 isn't gonna satisfy my taste

    Now, I saw I can get the ATI Radeon HD 4670 512 MB version for under $100 aftermarket so that's good, however, I'm willing to spend a bit more.

    So with that said, and being the mac virgin that I am, what are my options? I'm pretty sure there's no room for a SLI/Crossfire 2x or 3x setup in the iMac Not to mention upgrading the power supply.

    So if someone has any pointers of a site / guide or experience with upgrading Video card and what my options are, that'd be awesome.

    Thanks guys and I'm glad to be a MacDaddy finally Now I can never go back!

    -------------

    Addition/Edited:
    I forgot to mention. Although it's not that essential. I have TWO 24" screens that I'd like to hook up if possible. I know I can hook up 1 external monitor with the standard video card but which video cards that will be supported in my iMac will also have 2 external monitor slots? I'd like to be able to do something different on each monitor so splitting the 1 external VGA won't cut it

    Specs:
    Mac Pro, Power Mac G4, iMac G3, iPhone 3GS
    The iMac's video circuitry is not upgradable. The 256MB card will be just fine for Starcraft 2. The Zerglings will still look like Zerglings at 1280x800 :p

    Cool, thanks for the response although it wasn't the response I was hoping for hehe but simple enough.

    I can still buy and swap-in the 512 MB version I would presume right? No problems there?


    And what about a Mac Pro? I'm sure such a beast would have upgrade options for graphics cards right? Not that I have the money for it but it'd be good to know for the future

    No you cant upgrade the graphics card on a iMac. Its soldered onto the mainboard. If you want a new card you have to buy a new iMac. Or change the motherboard somehow...

    Or be an "expert" at removing soldered electronics and soldering a new one in place. I doubt very seriously that any after market board will a)be the proper size, b)have the proper connections and c)be flashed to work with the EFI found in your iMac.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    That is the way to go a Mac Pro. Towers are very upgradeable from optical and hard drives, graphics, memory etc all in the twinkling of an eye. These others are simply glossy toys of convenience IMHO.
