Not read the entire thread anyone give a brief update as to what's going on? From the few apges I've read the 970s dont use the entire 4GB for VRAM so people want to return them? Im gaming at 1080p so it won't affect me right?
Its not that not all of Vram is being used. its that the last 512 mb of it is gimped so it drops the bandwidth, causing performance to drop, resulting in stuttering, lack of smoothness, etc. This means only 3.5gb of Vram is running at full speed (bandwidth) effectively.
Nvidia are going through "flak avoidance" atm saying theres nothing wrong with the cards, they perform properly, but they didn't mention about the 512mb of gimped Vram and they've been found out so a lot of people here, and everywhere else for that matter, are a bit miffed that they've been mislead by Nvidia and are demanding some form of compensation/fix, etc.
Ocuk incidentally are doping a damn good job in helping out people who bought these GTX970 cards and deserve all the praise thye're getting, especially Gibbo,
