Wait til it comes out and you will see
And that's NOT why Nvidia gimped the memory controller. They did it so they could sell the 970 as a 4GB card when it should have been released as a 3.5GB card.
They did it to make more money from it, not to save money... if they wanted to save money, they would have sold it with 3.5GB... there's a difference there![]()
LOL, Sorry, but, your line of reasoning is really way off.
The 970 has 4GB of ram. It's has a 256 bit bus. It would have cost them more to change the configuration to address 3.5GB of memory than it would have to put 3.5GB fast + 512MB slow ram on the card.
It's why the 980Ti and Titan have 6GB and 12GB of ram because they have a 384 bit bus.
