So it appears that many iMacs with MXM cards are experiencing issues with dying cards.
We are going to jump in and do something about this. To begin we will offer direct replacement AMD cards. But as soon as our nifty new (OK, old) 27" iMac with 6970 gets here we will be working on Kepler cards from Nvidia. These run cooler and offer better performance.
We will be curious what the ,market will bear. With help from our brilliant staff programmer (Netkas) we could offer Maxwell/Pascal MXM cards. Question is, will anyone pay for these? Value of a 27" iMac of this era is below what any of these cards cost as PC cards so we will have to see.
Our European distributors will be authorized to sell these cards too. (One in UK, one in Poland) Please let us know if this is a product you want.
