NVIDIA only took the wraps off its its GM206-powered GeForce GTX 960 video cards last week, but now we're already being teased with the hint of 4GB models to be coming soon, as in just a few weeks away in March.
Computerbase is behind the rumor, posting a shot of Inno3D's latest offerings under their iChill range. As you can see, it says "4GB available in March - watch this space!", so unless Inno3D had this go out accidentally, or its a new form of guerrilla marketing, we know to expect GeForce GTX 960 cards to start shipping with 4GB of VRAM in March.
But even when, or if it happens, it will put the GTX 960 in a weird position. Unless AIBs can price them at under $250 (the GTX 960 with 2GB of VRAM sells for $199-$209) then it will be too close to the price of the GTX 970, which also has 4GB of RAM. I guess we'll see, with GTC 2015 kicking off in March, it could be the month for NVIDIA announcements, along with the rumored GeForce GTX Titan X.
