It’s been a pleasure waiting with you all… but we need not wait anymore! GTX 980M and GTX 970M are officially here and officially awesome. The first mobile GPUs to feature the Maxwell 2.0 architecture.
UPDATE (JAN 2015): GTX 965M joins the 900M team!
Have they ever supported G-sync?
The problem is that you need a PCB with controllers and stuff to do the G-Sync magic on notebook displays. So far I havent seen any notebooks with that. Who knows, maybe someone will add it this year?
