The new Apple iMac continues to remain in short supply, particularly if you want to customize your model. Weíve finally received our 27-inch iMac after waiting a solid four weeks from the time we ordered it, with current shipping times still showing a 3-4 week wait. Itís a highly specified model and includes a third-generation Core i7 quad-core CPU clocked at 3.4GHz, an Nvidia GeForce GTX 680MX with 2GB of VRAM and a 3-terabyte Fusion drive. We left the RAM at 8GB, and plan to upgrade that ourselves to save a few dollars.
