Last minute predictions before tomorrow: What do you guys think the new top-of-the-line iMac will receive for the GPU? Will it be the AMD Radeon HD 7970m or Nvidia GTX 680m? I honestly hope Apple will deliver the GTX 680m. The performance outperforms the AMD card (up to 15%) and features many more highlights, although the price will probably be the turning point to affect Apple's decision (About $300 more, a premium price tag compared to the 7970m).
