    hey guys, i realized there was a mistake order in iMac Custom that i ordered a year ago. i didnt choose the AMD R9 395X rather than R395 without X. is it possible to upgrade after all of this? cause its still kinda fresh to me i never use it for hard task or anything since this iMac bought for music studio but the studio didnt set up yet until June or July2017 i believe, the monitor plastic still there lol. is it too risk for upgrading such a VGA from AMD R9 395 to AMD R9 395X

    the point is: 1. is it possible to upgrade VGA after i purchased the iMac?
    2. is it too risky?
    3. do i need to worry about perfomance if there was human error while upgrading?
    4. does apple officialy claim this can be upgradeable after purchased?

    sorry my english bad.
    but thanks before!

    The graphics card can't be upgraded now, they are soldered on the motherboard. If you want a more powerful graphics card, you will need to buy a brand new iMac.

    But if it is for studio work, I don't think you will ever notice.

    The only difference is the VRAM amount, 2 GB instead of 4 GB. To be honest, you really won't notice much of a difference, if any at all, between the two. The extra VRAM only counts for tasks like gaming that rely heavily on the GPU.

    As for upgrading, it's pretty much not possible to do that. GPU and VRAM are soldered to the logic board.

    There are some technical differences between the two, namely the X has more shader cores (2048 vs 1792) and a slightly higher clock speed, but for all intents and purposes, the biggest difference is the doubled amount of VRAM. This link will give you a somewhat better idea if the difference is "worth it" to you for your needs.

    1: No
    2: N/A
    3: N/A
    4: NO, I believe the last the claimed as upgradable was the 2011

    If your softwar doesn't use the GPU for processing I would not worry too much, if it does ... there could be a noticeable difference as some audio software can put a very heavy load on GPU.
