Upgrade or Replacement:
These graphics cards can be used to upgrade your iMac for better performance or to replace a broken GPU. If your current graphics card is damaged, these models are perfect replacements.

Important Notes:

• Incompatible Processors: These graphics cards are not compatible with the 2009 A1311 and A1312 models using "Core 2 Duo" processors.

• X-Bracket Replacement:
  If you're replacing an HD6970M graphics card, you must replace the X-bracket. Failure to do so may cause a short circuit and damage the card. The buyer is responsible for any damage caused by improper installation.

• Display Issues After Installation:
  Some iMac models may experience a dimmer display or no startup screen, but this is rare. Most models will work fine, as the GPU is flashed for Mac. If issues occur, they can be fixed with OpenGL or OpenCore. Please do not buy if this concerns you.

• VBIOS Update:
  The VBIOS has been pre-configured for iMac and the card has been fully tested before shipping.

Payment Details:
Please make your payment within 24 hours of purchase to ensure a smooth transaction and timely shipping.
