It looks as though NVidia may be ceasing production of its high end GM chipsets and starting to get ready for Pascal chipsets ... might be a few bargains coming up
The first of the new Pascal architecture GPUs will be released later this month and early next month (GTX 1080 on May 27, GTX 1070 on June 10).
