Just perfect !
Very fast shipping to Europe !Swapped the old one (1Gb) by this new one (2Gb), works like a charm. Be patient to unplug all the cables on the motherboard, and unscrew it carrefully ! The procedure tooks me about 3 hours.Use fresh thermal paste to put on GPU, RAM Chips and few inductors & capacitances around (after celaning with isopropyl alchool).

    I could not be more happy about this replacement video card. It is every bit as good as the original with the added benefit that it is not the original brand which had a strong reputation for failure. Took me about an hour all up to exchange with a minimum of tools required. T10, T8 and T4 drivers, two suction cups and some silver heat transfer compound. The performance is equal or better than the original. I would highly recommend it for mid 2011 27" iMacs.

    Works wonderfully in my 27" iMac mid-2011. I would rate the install at an expert level since a full motherboard removal was required to get to the screws on the video card but the end result is worth it. I now have a mid-2011 iMac with 32Gb RAM, 1Tb SSD and the upgraded 2Gb AMD Radeon video card that will run macOS Catalina. Expedited shipping was reasonable as well.

    The price was right, the product arrived on time, was well packed, and worked as described performing to OEM standards. What more can be said? In an internet full of unscrupulous sellers and scammers, Maitlan is a good, honest outfit who provides a quality product! I will definitely be doing more business with them in the future

    Item as published.
    Looks new and, till now, working good, on an 27" iMac 2011, and recognised as original graphic card.
    Thought it coming from US, but it was from China, even though, it arrived the day it was supposed (DHL).
    Trusted seller, and I recommend the card.
    (Be advised about import taxes).
